Amatafari maremare ya alumina akorwa hamwe na chamotte ya bauxite yatoranijwe nkibikoresho fatizo byingenzi, ikarasa kuri 1450-1470 ° C hakoreshejwe uburyo bunoze kandi bugenzura neza. Amatafari maremare ya Alumina yakozwe hamwe na alumina cyangwa ibindi bikoresho fatizo birimo alumina nyinshi ikoresheje kubumba no kurasa. kubera kutagira aho ibogamiye imitungo ya alumina irashobora kurwanya aside irwanya isuri.
Genda Hitamo kandi ushungure chamotte kugirango deirone mbere yo kumeneka, irashobora kuzamura ubwiza bwamatafari ya alumina. Kuberako hari igipimo kinini cya grog mubigize ibintu bishobora kugera kuri 90 ~ 95%. Hitamo kandi werekane deironing mbere yuko grog ishenjagurwa.
Ukurikije ibintu bitandukanye bya Al2O3, Amatafari menshi ya alumina arashobora gushyirwa mubyiciro bitatu mubushinwa.
Icyiciro cya I Amatafari ya Alumina Yisumbuye afite ibice birenga 75% bya Al2O3.
Icyiciro cya II Amatafari ya Alumina Yisumbuye afite 60 ~ 75% ya Al2O3.
Icyiciro cya III Amatafari ya Alumina yo hejuru afite 48 ~ 60% ya Al2O3.
Amatafari maremare ya alumina afite ibintu byiza nkubushyuhe bwo hejuru, kwangirika gukomeye no kwambara, ubwinshi bwinshi, ibyuma bike, nibindi.

Amatafari maremare ya alumina arashobora gukoreshwa mu itanura riturika, amashyiga ashyushye, itanura ryamashanyarazi. kandi amatafari maremare ya alumina akoreshwa mubijyanye nicyuma nicyuma, idafite amabara, ikirahure, sima, ububumbyi, peteroli, imashini, amashyiga, inganda zoroheje, ingufu, ninganda za gisirikare nibindi.
