E jiri ya tụnyere ihe nkedo alumina dị elu na ihe nkedo mullite, corundum castable nwere ike arụ ọrụ dị elu ma na-eyi nguzogide, mana nkwụsi ike ọkụ ya adịghị mma ka nkedo mullite. Ịtinye obere mullite n'ime akụrụngwa nwere ike imeziwanye nguzogide ujo nke corundum castable. Corundum castable nwere nnukwu ike mkpakọ yana ezigbo nkwụsi ike nhazi. Ikike buru ibu, corundum castable nkedo lining nwere ezigbo nguzogide corrosion slag, nguzogide permeability, nguzogide dị elu na nguzogide siri ike na irighiri ihe siri ike, ntụ ntụ na oke ikuku gas.
