Indium oxide has a wide range of application fields and a large number of companies with global presence.

Indium oxide, also known as indium trioxide, is an inorganic compound with the molecular formula In2O3. It refers to the oxide of metal indium. It appears as a white or light yellow amorphous powder. It is insoluble in water and soluble in hot inorganic acids. Indium oxide has the advantages of large bandgap, low resistivity, and high catalytic activity. It is a new type of N-type transparent semiconductor functional material and can be widely used in glass, ceramics, chemical industry, optics, electronics, photovoltaics, military industry and other fields.

Specifically, glass, ceramics, and chemicals are the traditional application fields of indium oxide. In the above fields, indium oxide can be used in manufacturing scenarios such as transparent ceramics, high-temperature ceramics, electronic ceramics, special optical glasses, and high-efficiency catalysts; electronics and photovoltaics are the main applications of indium oxide. Application fields. In this field, indium oxide can be used in the manufacturing of electronic devices such as field effect transistors and optoelectronic devices as well as indium tin oxide (ITO) targets, transparent electrodes, solar cell conductive films and other semiconductor materials due to its high transparency and high conductivity. scene; in addition, indium oxide can also be used in the optical field. It has excellent transmittance and low dispersion and can be used in the manufacturing of optical components such as optical prisms and optical lenses.

According to the Industrial Research Center《In-depth market research and investment prospects of the indium oxide industry from 2023 to 2028 Predictive Analysis Report》shows that indium oxide has a wide range of application fields. Driven by the steady development of downstream industries, the global indium oxide market has shown an overall Steady growth trend. The global indium oxide market size will reach US$1.63 billion in 2022, a year-on-year growth of 4.2%.

From the production side, there are currently various production methods for indium oxide, including sol-gel method, hydrothermal method, co-precipitation method, hydrothermal synthesis method, thermal evaporation method, magnetron sputtering method, laser evaporation method, etc. Among them, the co-precipitation method is the current mainstream method for industrial production of indium oxide. It refers to using indium salts and alkali metal salts as raw materials to generate oxidation through mixing, co-precipitation, separation, washing, precipitation, drying, calcination, crushing, screening and other steps. Indium’s method has the advantages of simple operation, easy control, and low cost.

In addition, since indium is a rare precious metal with high price and low output, its production path can be produced through recycling and recycling methods in addition to chemical and physical methods, such as the method of using ITO waste to prepare regenerated indium oxide. The current layout Companies in the recycled indium oxide market include Guangxi Jinglian Optoelectronics and Kunming Pioneer New Material Technology.

Industry analysts said that there are a large number of indium oxide manufacturers around the world, mainly including South Korea’s Samsung, International companies such as South Korea’s LG, Japan’s Mitsui, and the United States’ Materion, as well as Zhuzhou Keneng New Materials, Zhuzhou Smelting Group, Shenzhen Xinzhoubang Technology, Anhui Dirac New Materials Technology, Kunming Pioneer New Materials, Shanghai Jinchao High Purity, and Anhui Nalomi Chinese companies such as Te New Materials, Haining Ruixin Electronic Ceramics, and Hebei Weixin Technology have fierce market competition.
