Chifukwa chiyani alumina ceramics imakhala yolimba kwambiri?

Ma ceramic a alumina ali ndi mphamvu yolimba yoteteza kutentha, makamaka chifukwa cha kapangidwe kake kapadera komanso mankhwala ake.

Choyamba, kapangidwe kake kakang'ono ka alumina ceramics ndi kapangidwe ka polycrystalline kopangidwa ndi tinthu tating'onoting'ono ndi maselo, zomwe zimapangitsa kuti ikhale ndi mphamvu zambiri zamakaniko. Chachiwiri, alumina ceramics ndi chinthu cholimba kwambiri, kuuma kwake kuli kofanana ndi diamondi, kovuta kuvala, kotero chimakhala ndi kukana kwakukulu kowawa. Chachitatu, mphamvu zamakaniko a alumina ceramics ndi zokhazikika kwambiri, pafupifupi zotsutsana ndi kuwonongeka kwa ma acid onse, maziko ndi mchere ndi zinthu zina zamakaniko, ndipo sizimakhudzidwa ndi dzimbiri la mankhwala.

Zoumba za alumina zimagawidwa m'magulu osiyanasiyana a ukhondo, ndipo kuchuluka kwa Al2O3 kumakhala kwakukulu mu zoumba za alumina za ukhondo wapamwamba. Kawirikawiri, kuchuluka kwa aluminiyamu kumakhala kwakukulu, komwe kumapangitsa kuti isamawonongeke bwino.

Kuphatikiza apo,zoumbaumba za aluminaKomanso imakhala ndi kukhazikika kwabwino kwambiri pa kutentha, imatha kusunga magwiridwe antchito abwino kwambiri kutentha kwambiri, zomwe zimapangitsa kuti nthawi zambiri ntchito yake ikhale yolimba komanso yosatha.

Chifukwa chake, makhalidwe awa a alumina ceramics amawapangitsa kuti azigwira ntchito bwino m'malo ambiri komwe kumafunika kukana kutopa.
