Refractory Grade

Luoyang Zhengjie

Series SR TYPE )

. Chrome Oxide Green(COG)'s chemical formula is Cr,O,.

. Bulk density is 5.21 g/cm", Moh's hardness is 8.5-9,close to the Corundum (AL,O,),Second only to diamond, while more than qurtz, Topaz and zinc

.Insoluble in water, acid or organic solvent, but can be slightly soluble in coRkfrated3dfm hydroxle sTn,soluble in hot sobim brmate soluion, hot concentrated perchloric acid solution or boiling sulphur&phosphorus mixed acid.

Stable to light atmosphere, and corrosive gases, has excellent weatherability. Melting point is 2265 c, boiling point is 3654 c, has excellent thermal stability. after high temperature buring COG is inert to acid and alkali, is the high-quality refractory material.

. Generally add in corundum or Corundum Spinel refractories, can improve the material of high temperature properties and Corrosion resistance to slag conspicuously.,etc.
