Bricks chromium dị ala magnesia chrome maka ngwakọta ciment na brik nke magnesia chrom na -ejikọ ọnụ.
Bricks Magnesia chrome bụ ngwaahịa na -agbanwe agbanwe nwere magnesium oxide (MgO) na chromium trioxide (Cr2O3) dị ka ihe mejupụtara ya, yana periclase na spinel dị ka ihe ndị bụ isi ịnweta. Ụdị brik a nwere nrụgharị dị elu, ike ọkụ dị elu, nguzogide siri ike na mbibi slag alkaline, nkwụsi ike dị mma nke ukwuu, yana ụfọdụ mgbanwe maka slag acid. Isi akụrụngwa maka ịme brik magnesia-chrome bụ magnesia na chromite. Ịdị ọcha nke akụrụngwa magnesia kwesịrị ịdị elu karịa ka o kwere mee. Ihe achọrọ maka ngwakọta kemịkal nke chromite bụ: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.
