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.
