Nhanganyaya yekurongwa kwe yakakwirira alumina refractory zvidhinha maererano nezviri muAl2O3

High alumina refractory zvidhinha zvakakamurwa kuva mamakisi matatu maererano nezviri Al2O3: Kirasi I (Al2O3> 75%); Kirasi II (Al2O3 ndeye 60% ~ 75%); Kirasi III (Al2O3 ndeye 48% ~ 60%). Maererano nekugadzirwa kwemaminerari, inogona kugoverwa kuva: low mullite (kusanganisira sillimanite) uye mullite (Al2O3 is 48% ~ 71.8%), mullite-corundum uye corundum-mullite (Al2O3 ndeye 71.8% ~ 95%), corundum (Al2O3) iri 95% ~ 100%) uye zvimwe zvidhinha zvinoramba.
