Chrome oxide green is mainly used for smelting metal chromium, chromium carbide, polishing paste and paint pigments, and also used as refractory materials, abrasive, enamel, glass, ceramic colorant and spray-paint materials.
Refractory grade chrome oxide green is a very high quality chrome oxide green with melting point up to 2300℃ and boiling point up to 3800℃. It used special calcination technics and additives to control certain metal ions, such as Fe, AL, to get required quality and function. It is commonly used in the production of refractory bricks used for metallurgical, glass as well as chemical industries.
