What is sodium pyroantimonate?

Sodium antimonate is also known as sodium pyroantimonate in China, and its molecular formula is. Sodium antimonate used to be mainly used in glass industry and cast iron enamel, etc. In recent years, with the development of science and technology, sodium antimonate has partially replaced antimony trioxide in some flame retardants and electronic products.Sodium pyroantimonate is a white powder, granular crystals and equiaxial crystals, high temperature resistance, in 1000 ℃ does not decompose, can be used as a high-grade glass clarifier and decolorant, plastics and textiles, flame retardants, enamel and ceramics, emulsifier and casting paint opaque paint. Sodium pyroantimonate is white or off-white crystalline powder, easily soluble in hot water, insoluble in cold water, insoluble in ethanol.In our country, the use of sodium antimonate was introduced from Japan in the 80's color TV tube glass production line only after the beginning. Sodium antimonate is also used as catalytic clarifier. At the beginning, the sodium antimonate used in the production of color TV picture tube glass in China was supplied by Japan, and after 1986, it began to use the sodium antimonate developed in China gradually.CharacteristicsSodium antimonate in some areas to replace antimony trioxide, mainly due to the following factors:(1) The use of sodium antimonate is cost-effective, and generally saves about 20% of the cost of raw materials.(2) Sodium antimonate is used as clarifier in special glass industry such as electronic tube, which can improve the transparency of glass.(3) When antimony trioxide is used as glass clarifying agent, it is necessary to convert trivalent antimony into pentavalent antimony, and antimony in sodium antimonate itself exists in the form of pentavalent antimony, which is quite favorable to the production.(4) the use of antimony trioxide as a glass clarifier must be added to sodium nitrate, while the use of sodium antimonate does not need to add sodium nitrate.(5) sodium antimonate coloring than antimony trioxide is much lower, and arsenic and lead content is also lower, used as a low coloring of plastics flame retardant is superior.(6) The antimony content of sodium antimonate is much lower than antimony trioxide, and the two are used in flame retardants and cast iron enameling and other aspects of the number and effect of the difference is not great, it can be seen that the use of sodium antimonate can reduce the consumption of antimony.Preparation method Firstly, sodium hydroxide and xylene trioxide instead of water are fully reacted, then ozone is passed, fully oxidized, recrystallized, centrifuged and dried, this invention uses ozone as oxidizing agent, with good oxidizing effect, and the method of microwave removal is used to obtain the sodium pyroximonate, and then the water of crystallization of the sodium pyroantimonate is removed by microwave, and finally, the pH is adjusted, and the drying, so as to get the neutral sodium metaantimonate. The water of crystallization of sodium pyroantimonate Chemicalbook can avoid high temperature yellowing of the generated sodium metaantimonate, adjust the sodium metaantimonate to neutral, and is more suitable for use as a flame retardant for polymer processing. The production process of the present invention is simple, short reaction time, environmentally friendly process, low production costs, gradually reduced, the preparation of sodium pyroantimonate and sodium metaantimonate obtained high purity, high whiteness, pH neutral, can be widely used as a flame retardant in the field of plastics. Uses1、Used as opaque filler, emulsifier for enamel and acid-resistant paint for iron and steel plate;2、It is used as the clarifier of high-grade glass such as picture tube and optical glass. It can resist exposure to sunlight and has good lampworking performance;3、It is used as flame retardant for textiles, plastics, rubber and other industries;4、Used in engineering plastics pending industry with low coloring power, saving pigment; used in enamel and acid-resistant ceramics, high-grade ceramics.5、It is used for identifying sodium ion in chemical analysis.

Most photovoltaic glass companies choose sodium pyroantimonate as clarifying agent

       Most of the photovoltaic glass enterprises choose sodium pyroantimonate as a clarifying agent, due to sodium pyroantimonate in the decomposition temperature within the country, do not have to go through the transformation from low to high valence, can be directly decomposed to release oxygen, is an excellent glass clarifying agent. Practice has proved that the role of sodium pyroantimonate clarification is mainly concentrated in 1400 ~ 1450 ℃ question, at 1450 ℃ to maintain 40 ~ 50min, the glass liquid can be fully clarified.       In the glass manufacturing industry, sodium pyroantimonate and antimony trioxide is also used to manufacture a variety of properties and uses of glass, such as optical glass, infrared transmission glass and chemical fiber glass, the use of solar energy heat reflection glass. Sodium pyroantimonate is an excellent clarifier and decolorizer for high-grade glass, as the ferrous oxide of the lime green pigment in glass, affecting the color and transparency of the product, sodium pyroantimonate is needed as a clarifier, so that the iron oxide is converted to iron trioxide, the impurity disappears and the glass is clarified. Manganese is also added to the material, manganese nitrate, manganese nitrate oxygen discharge temperature is also in the 1400-1450 ℃, it is decomposed at high temperatures after the production of O2 and SO2 on the growth of bubbles and dissolution plays an important role. As the clarification temperature of the two clarifiers is concentrated in the same temperature range, so it can play a good role in clarification. This is also for the development of the clarification temperature for the theoretical basis. Conventional calendered glass its clarifying agent for manganese nitrate in the use of the process needs to be pre-mixed with a certain amount of coal dust before use, due to the production of ultra-white calendered glass its coal dust will make the glass liquid iron oxide reduced to ferrous oxide or iron sulfide, so that the glass becomes yellow glass affecting the transparency of the glass. So the production of ultra-white calendered solar photovoltaic glass does not use coal dust, appropriately increase the amount of nitrous oxide but increase the amount of use shall not exceed 0.5% of the amount of glass. If other clarifiers are used to reduce the use of nitrate available sodium nitrate, sodium pyroantimonate, antimony trioxide, etc..       The demand for sodium pyroantimonate and the quality of sodium pyroantimonate have put forward a high level of essentials. Among them, the dosage of sodium nitrate can not be too high. Its decomposition of gas nitrogen oxides is difficult to deal with. Diantimony oxide, manganese nitrate, sodium nitrate can be used as a clarifying agent according to the corresponding proportion of the mixture. The total proportion does not exceed 1.1% or so. At present, the glass factory produces super white glass with composite clarifying agent is more. To reduce production costs and reduce the emission of exhaust gas has a positive significance. There are also production of ultra-white calendered photovoltaic glass production plant to ensure that the clarification and glass transmittance, its conventional ratio of clarifying agent usage is: nitrate, sodium nitrate, sodium pyroantimonate its ratio of: 0.6: 0.2: 0.2 = 1% so according to the 100Kg of dry base material calculated as the total amount of 1Kg. production scale output amount of 250 td of glass kiln, which 30% of the broken glass dosage. The mix dosage is 82.682% conversion rate to glass liquid, i.e. 212 td of mix is required. The daily amount of integrated clarifier for 19%, 2.12t sodium nitrate to 0.2 ratio taken as 424Kgd. By calculating the hourly emissions from the exhaust gas 170mg/m3, so its nitrogen oxides emissions are completely less than the national regulations of 70omgm3 emissions.

CICC: PV antimony demand accelerated growth, antimony prices are expected to return to the upward channel with demand recovery

CICC released a research report said that at the beginning of 2021, the demand for antimony for photovoltaic accelerated growth, in the context of supply rigidity, antimony ingot inventory continued to depolymerize, antimony prices began to move up. At the end of February to early April this year, weak demand for antimony prices only 5% of the retracement, has been compared with the lowest point in April back to 2%. Standing at the current point in time, antimony prices at home and abroad have stabilized signs of recovery. The bank believes that in the antimony ore supply rigidity, antimony ingot inventory history of the lowest background, antimony prices are expected to recover with domestic demand back to the upward channel.Antimony: "less but fine" strategic new energy metal. First, antimony has low abundance in the crust of metal elements, only higher than indium, laying the foundation for its scarcity. According to USGS, antimony in the global / China's static reserves and mining ratio was as low as 17 / 6 years. Secondly, antimony is indispensable as "industrial monosodium glutamate" and has been listed as a strategic mineral resource by many countries. Third, one of the antimony products, sodium pyroantimonate, as a photovoltaic glass clarifier optimal solution, its new energy properties are gradually revealed.Antimony ore supply is rigid, regenerated antimony is difficult to have a large increase in the short term. First, China's antimony mines in production face declining grade, resource depletion and other issues, and the lack of backup resources, resulting in a decline in mine production from 180,000 tons in 2008 to 60,000 tons in 2022. According to the bank, considering the reduction of producing mines and the small expansion of Huaxi Mining, the future domestic supply may be maintained at 60,000 tons/year. Secondly, according to the bank's statistics, among the 20 antimony mining projects in stock overseas, 18 of them are facing the problem of production decline or shutdown, and only 2 small antimony mines are temporarily stable in production, and the future increment is only Huayu Mining Tarkin project and Russia FEA antimony mining project. Third, the domestic and overseas recycled antimony market polarization, overseas recycling has basically mature, domestic recycling in the short term is difficult to breakthrough progress, the bank is expected to 2022-2025 recycled antimony supply CAGR of about 1.6%.Riding on the east wind of photovoltaic development, downstream demand is systematically improving. First, sodium pyroantimonate clarifies well and accounts for less than 0.3% of the cost of photovoltaic components, which is currently difficult to be replaced. According to the bank's calculations, with the global new PV installed capacity of high-speed growth, and double-sided double-glass component penetration rate increase, 2022-2025 antimony demand in the field of photovoltaic CAGR is expected to reach 30%. Secondly, the bank believes that the traditional areas such as flame retardants and lead-acid batteries are expected to have favorable demand for antimony as the domestic economy recovers. The bank conservatively assumed that the flame retardant field due to antimony prices continue to rise and a small substitution scenario, bromine flame retardants accounted for from 21% in 2021 to 17% in 2025, overall, antimony 2022-2025 total demand CAGR of about 5.5%.Looking ahead to the next three years, global antimony supply and demand is expected to remain tight, driving antimony price pivot upward. In view of the traditional demand with the economic recovery gradually pick up, photovoltaic antimony rapid growth, superimposed on the global antimony ore supply rigidity, the bank expects the global antimony supply and demand is expected to maintain tight pattern, 2023-2025 antimony supply and demand gap of -0.7, -0.8, -0.9 million tons, respectively, supply and demand continue to tighten the supply and demand is expected to drive antimony price pivot to the upside.Original address: https://new.qq.com/rain/a/20230605A0229I00
