[chemical] Cr2O3
Chrome oxide green by chromic acid, sodium bichromate (or potassium) and sulphur by calcination. The thermal decomposition of the ammonium dichromate or. High temperature resistance, light resistance, resistance to various chemicals. Products of pure natural chlorophyll near infrared reflectance (Al2O3) close to the Mohs hardness only to diamond, corundum. With metallic luster, with magnetic, strong hiding power, high temperature resistant, resistant to sunlight, insoluble in water, soluble in acid, in the atmosphere is relatively stable, did not affect the concentration of acid and alkali and sulfur dioxide gas, is to highlight the excellent quality of pigment and fastness. Insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, dissolved in hot sodium bromate solution and heat concentrated perchloric acid solution or boiling parathion mixed acid. The light, atmosphere, and corrosive gases (H2S, SO2, etc.) are extremely stable and good weather resistance. In case of thermal stability, is the quality of refractory materials. Chromic oxide mainly used in metallurgy, paint, polishing, refractory materials and new development of the molten coating etc..
