Chromium Carbide ntụ ntụ na-ebubata ịdị ọcha dị elu
Nkọwa ngwaahịa
Chromium carbide metal chromium (chromium trioxide) na carbon bụ carbonized n'ime oghere.Usoro ihe omimi ya bụ Cr3C2 (pasent dị arọ nke carbon bụ 13%), njupụta ya bụ 6.2g/cm3 na isi ike dị n'elu HV2200.Ọdịdị nke chromium carbide ntụ ntụ bụ ọlaọcha gray.Chromium carbide ntụ ntụ bụ nnukwu agbaze ebe inorganic ihe na-eji mma na-eyi nguzogide, corrosion eguzogide na oxidation iguzogide na elu okpomọkụ gburugburu (1000-1100 degrees).
