Udupira two gusya twa alumina 92%Bikozwe ahanini mu ifu ya alumina, byongewemo ingano nto ya okiside y'icyuma, hanyuma bigakorwa binyuze mu gushyushya cyane. Bifite ishusho y'uruziga kandi biza mu bunini butandukanye, bifite uburebure busanzwe buri hagati ya mm 0.5 na cm 10. Iki gicuruzwa gifite ubukana bwinshi, kidapfa kwangirika neza, kidapfa kwangirika cyane, kandi gifite imbaraga ziciriritse za mekanike. Ubunini bwacyo busanzwe buri hagati ya g 3.6 na 3.7/cm³, kandi ubukana bwa Mohs bushobora kugera kuri 9. Bitewe n'imiterere yacyo idahindagurika ya kristu, kigumana igipimo gito cyo gushonga mu gihe kirekire, kikarinda kwanduza ibikoresho byo mu butaka.
Imipira yo gusya alumina ikoreshwa cyane mu gutunganya umupira mu nganda nko gusiga, ibikoresho by'ubwubatsi, imiti, na ceramic. Mu gihe cyo gutegura glaze za ceramic, zishobora kugabanya neza ingano y'uduce tw'ibikoresho no gukumira kwanduza icyuma; mu nganda za sima, zikoreshwa mu gusya slag na clinker; mu gukora ceramics z'ikoranabuhanga n'ibikoresho bya rukuruzi, ubuziranenge bwazo n'ubudahangarwa bwazo byemeza ubwiza bw'ibikoresho by'ifu y'ubutaka. Byongeye kandi, mu gusya amarangi, amarangi, na electrodes nziza n'imbi za bateri za lithium, kubera ko ibyuma byo gusya alumina bifite ubudahangarwa bwiza bwa aside na alkali, bishobora kuba igikoresho cy'ingenzi cyo gusya.
Guhitamo imipira yo gusya ya alumina ifite ubuziranenge bwa 92% bisaba gusuzuma neza ibipimo byinshi bya tekiniki. Ubwa mbere, ingano nyayo ya alumina n'ubucucike bw'ingano bigomba kugeragezwa kugira ngo bigenzure ibipimo bya 92% by'imiterere n'urwego rw'ubucucike bw'abahanga. Icya kabiri, ubudahangarwa bw'ubudahangarwa bugomba gusuzumwa binyuze mu isuzuma ry'ubudahangarwa, akenshi hakoreshejwe igipimo cyo kwambara kuri buri gihe cyangwa garama z'ibikoresho byatakaye kuri toni yo gusya nk'ibipimo by'ubunini. Byongeye kandi, ubuso bumeze neza kandi buzunguruka bugomba kureberwa kugira ngo hirindwe ko hagira imyanda, imyenge cyangwa imiterere ihindagurika.
