Brick silica refractory bụ acid refractory ma nwee ezigbo acid slag mbuze na-eguzogide. Slica brik refractoriness n'okpuru ibu bụ ruo 1640 ~ 1690 ℃, pụtara ìhè mbido nro okpomọkụ bụ 1620 ~ 1670 ℃ na ezi njupụta bụ 2.35g/cm3. Brick ọkụ silicon nwere ike ịrụ ọrụ na oke okpomọkụ ruo ogologo oge ma mee ka olu kwụsie ike na-enweghị mgbanwe. Brick reractory silicon nwere ihe karịrị 94% ọdịnaya SiO2.
