Chromium oxide green [Chinese name] chrome oxide green [English name] oxide green chrome, oxide green chromium [alias] s N Y N have a Cr2O3 and Hu, R and S [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.. Physical and chemical index Syngony Six party system colour Green powder Chemical formula Cr2O3 molecular weight One hundred and fifty-one point nine nine density 5.21g/cm3 Mohs hardness 8.5-9 Refractive index Two point five Specific heat (20 degrees C) /0.17J/ (g, K) melting point 2265 degrees C boiling point 3000 degrees C Chromium oxide green application Chrome oxide green for smelting metal chromium and chromium carbide, enamel, ceramics, glass, artificial leather, refractory materials, building materials, coloring, catalysts for organic synthesis, manufacturing fast material and the printing of paper money in the special ink, metal polishing abrasive materials, metal surface infiltration chromium, magnetic materials. Used in coatings, ceramics, rubber, fine arts pigments, and camouflage coatings.

1, in the building materials industry is mainly used in colored cement, color cement tile, color cement tile, glazed tile and floor tile, color mortar, color asphalt concrete, terrazzo, mosaic tiles, artificial marble and metope paint, etc.; 2, used in a variety of coatings to protect material and color, external walls including waterborne coatings, powder coatings, etc.; it also can be used in paint including epoxy resin, alkyd, amino and so on all kinds of primers and paint; can also be used for toy paint, decoration paint, furniture paint, electrophoresis paint and enamel. Iron red primer has the antirust function, can replace expensive red lead paint, save non-ferrous metals. 3, used for plastics coloring, such as thermosetting plastics and thermoplastic plastics, coloring and rubber products, such as automobile inner tube, inner tube, bicycle inner tube, etc. 4, used for advanced fine grinding materials, used in precision hardware instruments, such as optical glass polishing. High purity is the main basic material of powder metallurgy, used for smelting various magnetic alloy and other advanced alloy steel. By ferrous sulfate, iron oxide yellow or waste iron mixed by high temperature calcination, or directly from the liquid medium is made.
