Magnesia aluminom brik
nkọwa
Magnesia-alumina brik: Magnesia alumina spinel brik bụ alkaline refractory na periclase na spinel dị ka isi mineral, nke a na-etolite site na ịkpụzi nrụgide dị elu na ikpo ọkụ dị elu.N'otu oge ahụ, a na-agbakwunye mineralizer kpọmkwem iji jikọta akụkụ kristal nke ngwaahịa ahụ ozugbo.
Atụmatụ
Ọ na-ji elu okpomọkụ chemical corrosion eguzogide, magburu onwe alkali iguzogide, elu ibu nro okpomọkụ, ezi thermal ujo kwụsie ike, ike mbuze eguzogide, na ezi elu okpomọkụ ọrụ arụmọrụ.
Ngwa
A na-ejikarị ya na mpaghara mgbanwe nke elu na nke ala nke ciment rotary kiln na ngwa ngwa nke na-achọ nnukwu nguzogide okpomọkụ na nguzogide okpomọkụ.
