Libolo tsa Alumina tsa ho Sila
Tlhaloso ea Sehlahisoa
Libolo tsa ho sila tsa Alumina,tse entsoeng ka aluminium oxide (Al₂O₃) e le karolo ea tsona ea mantlha 'me li sebelisa mokhoa oa ho sila ka letsopa, ke libolo tsa letsopa tse sebetsang tse etselitsoeng ka ho khetheha ho sila, ho sila le ho qhalanya thepa. Ke e 'ngoe ea mecha ea ho sila e sebelisoang haholo lits'ebetsong tsa ho sila tsa indasteri (joalo ka li-ceramic, li-coat le liminerale).
Libolo tsa alumina tse silang li arotsoe ka mefuta e meraro ho latela bongata ba tsona ba alumina: libolo tsa aluminium e mahareng (60%-65%), libolo tsa aluminium e mahareng (75%-80%), le libolo tsa aluminium e phahameng (kaholimo ho 90%). Libolo tsa aluminium e phahameng li arotsoe hape ka lihlopha tsa 90-ceramic, 92-ceramic, 95-ceramic, le 99-ceramic, 'me 92-ceramic ke eona e sebelisoang haholo ka lebaka la ts'ebetso ea eona e phahameng ka kakaretso. Libolo tsena tsa ho sila li na le bothata bo phahameng (bothata ba Mohs ba 9), boima bo phahameng (kaholimo ho 3.6g/cm³), ho hanyetsa ho tsofala le ho bola, le ho hanyetsa mocheso o phahameng (1600°C), e leng se etsang hore li lokele ho siloa hantle ha li-glaze tsa ceramic, lisebelisoa tse tala tsa lik'hemik'hale le liminerale tsa tšepe.
Likaroloana:
Ho ba thata le ho hanyetsa ho apara ka matla:Bothata ba Mohs bo fihla ho 9 (haufi le daemane), ka sekhahla se tlase sa ho tsofala (<0.03%/1,000 lihora bakeng sa mehlala e hloekileng haholo). E hanela ho robeha le ho thothomela ha e siloa ka nako e telele, e leng se fellang ka bophelo bo bolelele ba ts'ebeletso.
Botebo bo Holimo le Bokgoni bo Holimo ba ho Sila:Ka bongata ba 3.6-3.9 g/cm³, e fana ka matla a matla le ho beola nakong ea ho sila, e ntlafatsa thepa kapele ho fihlela boemong ba micron, ka katleho e phahameng ka 20%-30% ho feta libolo tsa aluminium tsa maemo a mahareng le a tlase.
Litšila tse Tlase le Botsitso ba Lik'hemik'hale:Mehlala e hloekileng haholo e na le litšila tse ka tlase ho 1% (joalo ka Fe₂O₃), e thibelang tšilafalo ea thepa. E hanela boholo ba li-acid le li-alkali (ntle le li-acid tse matla le li-alkali tse kopaneng), mocheso o phahameng (kaholimo ho 800°C), 'me e loketse mefuta e fapaneng ea litsamaiso tsa ho sila.
Boholo bo Tenyetsehang le ho Sebeletsana:E fumaneha ka bophara ho tloha ho 0.3 ho isa ho 20 mm, bolo e ka sebelisoa ka boholo bo le bong kapa bo tsoakiloeng, e tsamaellana le li-ball mill, li-sand mill le lisebelisoa tse ling, e fihlela litlhoko tsohle ho tloha ho tse thata ho isa ho tse silang hantle.
