La description

chromium oxide green powder manufacturer

PRODUCT DESCRIPTION
Chrome oxide green , MF Cr2O3 ,Light green powder, Density 5.*1 g/cm3,  Mohs hardness 8.5 ~ 9, close to the corundum(Al2O3), second only to diamond, while more than quartz SiO2, topaz Al2 [SiO4] (F, OH) 2 and zircon ZrSiO4). Refractive index 2.5 (great hiding powder), specific heat capacity (*0 ℃) / 0.*7 J/low K (g). Insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, soluble in hot sodium bromate solution , hot concentrated perchloric acid solution or boiling sulfur phosphorus mixed acid. Stable to light, atmosphere, and corrosive gases (H2S, SO2, etc.), has excellent weather resistance, thermal stability.

Melting point ***5℃, boiling point ***4℃, thermal stability, after high temperature burning, chrome oxide green act inertness to acid and alkali ,is great refractory material. Generally add in corundum or corundum spinel refractory materials, can significantly improve the material of high temperature strength, resistance to slag erosion, etc.
