Application
1.Chromium oxide green holds an important position in the field of inorganic pigments. Widely used in ceramic enamel, coatings, inks, special paints, green flooring, green glass and other fields.
2.Chromium oxide green, which has been burned at high temperatures, is inert to both acids and bases. It is a high-quality refractory material that can significantly improve its high-temperature strength performance, slag erosion resistance, and other properties.
3.Widely used in fields such as non-ferrous metallurgy, building materials, petrochemicals, large-scale power generation boilers, and waste incinerators.
4.It can also be used as a melt blown coating, directly sprayed onto the surface of metals, ceramics, etc. with high-temperature plasma gas, endowing the latter with extremely high wear resistance, corrosion resistance, and high temperature resistance.
5.Can be made into polishing materials, widely used for grinding and polishing stainless steel, gemstones, precision machinery, etc.

Indium is a white metal, extremely soft, extremely malleable and ductile. Cold weldability, and other metal friction can be attached, liquid indium excellent mobility. The metal indium is not oxidized by air at normal temperature, the indium starts to be oxidized at about 100℃, (At temperatures above 800 ℃), indium burns to form indium oxide, which has a blue-red flame. Indium is not obviously harmful to human body, but soluble compounds are toxic.
