Udupira two gusya twa Alumina Ceramic dufite aluminiyumu nyinshi: Ibyuma byo gusya bifite imikorere myiza

Alumina ifite aluminiyumu nyinshiimipira yo gusya alumina ceramicni ibikoresho bya keramike bigezweho bigizwe ahanini na okiside ya aluminiyumu (Al₂O₃), akenshi bifite ingano irenga 90%. Bigaragaza ubukana bwinshi, kudashira neza, kudahinduka neza mu binyabutabire, kandi bikaba bike mu kwanduza, bigatuma bikoreshwa cyane mu nganda zisya cyangwa zumye nka keramike, amarangi, imiti, ubucukuzi bw'amabuye y'agaciro, n'ibikoresho by'ikoranabuhanga. Bifite ubucucike buri hejuru ya 3.6 g/cm³ kandi ubukana bwa Vickers bugera kuri HV1500 cyangwa irenga, byongera cyane imikorere myiza yo gusya mu gihe bigabanya ikoreshwa ry'ibikoresho.

Ibyiza byabyo by'ingenzi biri mu kunoza cyane imikorere yo gusya no kunoza ubukungu. Ubukana bwinshi (Mohs grade 9) butuma ibikoresho bikomeye bihinduka vuba; imiterere imwe itanga imbaraga zihoraho kandi ikongera igihe cyo gukora. Ubukana bwiza bw'ibinyabutabire butuma birwanya aside ikomeye na alkali, bikarinda kwanduza ibikoresho byo mu butaka. Ibisigazwa by'icyuma bike cyane (ubusanzwe biri munsi ya 0.01%) bituma biba byiza cyane mu bikorwa byoroshye, nko mu bikoresho bya bateri ya lithiamu, glaze nziza, na ceramics z'ikoranabuhanga.

Uburyo bwo gukora bukubiyemo gutegura ifu igenzurwa neza, gukanda isostatic, no gushyushya cyane kugira ngo habeho ubucucike bwinshi, habeho imyenge mike kandi habeho gukomera cyane. Igenzura ry’ubuziranenge rikubiyemo uburyo bwo gukora neza, imiterere y’ubugari, ubukana, no kudakora neza kugira ngo huzuzwe ibisabwa n’ibikoresho bitandukanye byo gusya n’imiterere y’imikorere. Guhitamo neza ibipimo (urugero: uburebure kuva kuri mm 1 kugeza kuri mm 50) n’ibipimo byo kuzuza bishobora kunoza uburyo bwo gusya no gukoresha ingufu neza.

Bitewe n’uko hakenewe cyane ingano y’uduce duto kandi hagakoreshwa ubuziranenge bwinshi mu kuvugurura inganda, imipira yo gusya ya alumina ifite alumina nyinshi yabaye igikoresho cy’ingenzi cyo gusya mu nzego za none z’ibinyabutabire n’ibikoresho bishya. Mu kongera ireme ry’ibicuruzwa no kugabanya ikiguzi rusange, bitanga igisubizo cyizewe cya tekiniki ku nganda zitunganya neza. Mu gihe kizaza, kunoza imiterere y’ibikoresho no gutera imbere mu ikoranabuhanga ryo guhindura ubuso bizarushaho kwagura uburyo bikoreshwa.
