Iph powder ye-alumina e-calcined yenziwe ngama-aluminium hydroxide embonini noma i-aluminium oxide embonini njengezinto zokwakha, futhi icalcined ekushiseni okufanele ukuze kwakhiwe umkhiqizo we-alpha alumina ozinzile; I-aluminium oxide micro powder eyenziwe ngama-alpha alumina e-calcined njengezinto zokwakha futhi ibhalwe ngembobo. Iph powder ye-alumina e-calcined ivamise ukusetshenziswa emikhiqizweni ye-refractory ehlosiwe efana nezikebhe, izingxenye ezintathu ezinkulu, namabhulokhi e-corundum, noma ngokuhlangana ne-alumina esebenzayo ukuze kube nezinto ze-refractory ezingezona ezibhalwe phansi.
Lapho kusetshenziswa uthuli lwe-alumina olushisiwe ukukhiqiza imikhiqizo ehlanganiswe ne-resin, okuqukethwe kwamanzi kwayo kuphansi, kulula ukuhlanganisa kahle, futhi ukuzinza kwayo kokuphakama kuphezulu. Uma kusetshenziswa ndawonye ne-micro powder ye-alumina esebenzayo noma i-silica fume ukuze kutholakale izinto eziphikisana nezinga eliphakeme, kungafinyelelwa ekusatshalalisweni kwezinsimbi eziseduze kakhulu noshukela omncane, kuncishiswe ukwengeza amanzi nokuphuma, kwehliswe izinga lokushintsha okuqondile, futhi kwandiswe amandla.
