Antimony oxide has a wide range of applications. my country is the world’s major producer.

Antimony oxide is an important inorganic compound, which refers to a compound composed of antimony and oxygen elements. There are two main types: antimony trioxide (Sb2O3) and antimony pentoxide (Sb2O5). Antimony trioxide appears in the form of white cubic crystals, soluble in hydrochloric acid and tartaric acid, and insoluble in water and acetic acid; antimony pentoxide appears in the form of light yellow powder, insoluble in water and slightly soluble in alkali, and can generate antimonate salts.

There are various production methods for antimony oxide. Among them, antimony trioxide is mainly prepared by the antimony metal oxidation method (fire method). It refers to the method of using antimony metal powder as raw material, heating it to high temperature, and then introducing oxygen to produce antimony oxide. , and the antimony oxide produced by the fire method can be further purified through filtration, washing, drying and other links; antimony pentoxide is mainly prepared by the antimony trioxide oxidation method, which refers to using antimony trioxide as raw material and nitric acid or Hydrogen peroxide is used as an oxidant, and is added to a reflux reactor to undergo an oxidation reaction to generate antimony pentoxide.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Antimony Oxide Industry 2023-2028” released by the Industrial Research Center, antimony oxide It is an important chemical raw material that can be widely used in ceramics, glass, plastics, rubber, chemical industry, papermaking, environmental protection, electronics and other fields. Currently, driven by the rapid development of the downstream market, my country’s demand for antimony oxide continues to increase.

Specifically, in the field of glass, antimony oxide can be used as a defoaming agent for melting glass and removing bubbles, and can also be used as an opaque agent in glass and ceramic production scenarios to make visible light except long-wave infrared light opaque; in the chemical industry In the field of electronics, antimony oxide can be used as a catalyst in polyester fiber production scenarios, and as a passivating agent in petroleum catalytic cracking and catalytic reforming processes; in the electronics field, antimony oxide can be used in the manufacturing of electronic devices such as transistors and diodes; in In the field of plastics and rubber, antimony oxide can be used as a flame retardant, fire retardant, etc. to improve the performance of plastics, rubber and other materials.

Globally, the main producing countries of antimony oxide are China, Russia, South Africa, Kyrgyzstan, etc. my country is rich in antimony ore resources, and with the continuous improvement of domestic antimony resource smelting and processing technology, it has gradually become the world’s leader in antimony resources and antimony smelting, with huge market development potential.

Industrial analysts said that the main domestic antimony oxide manufacturers include Guizhou Huaxing Metallurgy and Shanghai Shaosong Flame Retardant , Guangxi Nanguo Metal, Hunan Gold, Hunan Nonferrous Metals, Hubei Zhongtimony Chemical, Wuxi Zhengmao Chemical, Shandong Bairui Chemical, Guangxi Rixing Metal Chemical, Guangxi Shengfu Antimony Industry, Hubei Yongcheng Industrial, etc. As the world’s major antimony oxide producer, my country is currently highly dependent on my country’s antimony oxide imports from other countries in the world. For example, the United States’ dependence on China for antimony oxide demand is about 40%. Overall, there is broad market development space for antimony oxide in my country.
