Aluminium oxide ndi mankhwala a aluminiyamu, chinthu chopangidwa ndi aluminiyamu ndi mpweya. Amatchulidwa ndendende kuti aluminium oxide ndipo ndi omwe amapezeka pafupipafupi mwa ma aluminium oxides. Kuphatikiza pa kudziwika kuti aluminiyamu, imatha kupitanso ndi mayina a aloxide, aloxite, kapena alundum, kutengera mawonekedwe ake ndikugwiritsa ntchito. Nkhaniyi ikuyang'ana kwambiri ntchito ya aluminiyamu m'munda wa ceramic.
Zida
Zida zina zamthupi zimagwiritsa ntchito mbale za alumina ceramic, zomwe nthawi zambiri zimathandizidwa ndi aramid kapena UHMWPE, kuti zithandizire polimbana ndi ziwopsezo zambiri zamfuti. Komabe, sizimaganiziridwa kuti ndi zankhondo. Kuphatikiza apo, imathandizira kulimbitsa magalasi a alumina motsutsana ndi zipolopolo za .50 BMG.
Biomedical Applications
Gawo lazachilengedwe limagwiritsa ntchito kwambiri zoumba za alumina chifukwa cha kudalirika kwawo komanso kulimba kwawo motsutsana ndi kuvala ndi dzimbiri. Alumina ceramic imagwira ntchito ngati zida zopangira mano, zolowa m'malo, ndi zida zina zamankhwala.
Zonyansa
Zida zambiri zotayira m'mafakitale nthawi zambiri zimagwiritsa ntchito alumina chifukwa cha mphamvu zake zapadera komanso kuuma kwake. Pamlingo wa Mohs wa kuuma kwa mchere, mawonekedwe ake opezeka mwachilengedwe, corundum, amayesa 9 - pansi pa diamondi. Mofanana ndi diamondi, munthu akhoza kuvala alumina kuti asawonongeke. Okonza mawotchi ndi opanga mawotchi amagwiritsa ntchito Diamantine, mu mawonekedwe ake a ufa (woyera), monga chopukutira chapamwamba kwambiri.
Zoteteza
Alumina ndi insulator yapamwamba kwambiri, yomwe imapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamatenthedwe apamwamba komanso mamagetsi apamwamba. Amagwiritsidwa ntchito ngati gawo lapansi (silicon pa safiro) komanso chotchinga chotchinga m'mabwalo ophatikizika kuti apange zida zapamwamba kwambiri monga ma transistors amagetsi amodzi, zida za superconducting quantum interference (SQUIDs), ndi ma superconducting qubits.
Kupera
Gawo la ceramics limagwiritsanso ntchito alumina ngati sing'anga yopera. Alumina ndiye chinthu chabwino kwambiri chogwiritsidwa ntchito pogaya chifukwa cha kuuma kwake komanso kukana kuvala. Mphero za mpira, mphero zogwedera, ndi makina ena opera amagwiritsa ntchito alumina ngati mphero.
Mapeto
Ngakhale aluminiyamu imadziwika kuti imagwiritsidwa ntchito popanga aluminiyamu, imakhalanso yofunika kwambiri m'minda yambiri ya ceramic. Ndiwofunika kwambiri pazogwiritsira ntchito izi chifukwa cha malo ake osungunuka, matenthedwe apamwamba komanso makina amakina, zoteteza, kukana kuvala, komanso kuyanjana kwachilengedwe.
