Alumina ceramic ndi mtundu wa alumina (Al2O3) ngati chinthu chachikulu cha ceramic, chomwe chimagwiritsidwa ntchito mumayendedwe ophatikizika amakanema.Alumina ceramics ali ndi ma conductivity abwino, mphamvu zamakina komanso kukana kutentha kwambiri.
Zoumba za aluminiyamu pakali pano zimagawidwa m'mitundu iwiri: chiyero chachikulu komanso chofala.Kuyeretsedwa kwakukulu kwa alumina ceramic kumaposa 99.9% Al2O3 zomwe zili muzinthu zadothi, chifukwa cha kutentha kwake mpaka 1650-1990 ℃, kufalikira kwakutali kwa 1 ~ 6μm, komwe kumapangidwa ndi galasi losungunuka kuti m'malo mwa platinamu crucible.Chifukwa cha transmittance kuwala ndi kukana dzimbiri zitsulo zamchere, angagwiritsidwe ntchito ngati sodium nyali chubu, mu makampani zamagetsi angagwiritsidwenso ntchito ngati Integrated dera bolodi ndi mkulu pafupipafupi kutchinjiriza zakuthupi.
Ma aluminiyamu wamba amagawidwa mu 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain ndi mitundu ina molingana ndi zomwe zili mu Al2O3, nthawi zina zomwe zili mu Al2O3 mu 80% kapena 75% zimawonedwanso kuti ndi mndandanda wamba wa alumina ceramic.Pakati pawo, 99 alumina ceramic zipangizo ntchito kupanga mkulu kutentha crucible, ng'anjo chubu ndi wapadera kuvala zosagwira zipangizo, monga fani ceramic, ceramic zisindikizo ndi mavavu madzi, etc. 95 aluminiyamu ceramic zinthu makamaka ntchito ngati dzimbiri kugonjetsedwa, kuvala kugonjetsedwa. magawo;85 alumina ceramic zakuthupi nthawi zambiri zimasakanizidwa ndi gawo la talc, kusintha mphamvu zamagetsi ndi mphamvu zamakina, ndipo zimatha kusindikizidwa ndi molybdenum, niobium, tantalum ndi zitsulo zina, zina zimagwiritsidwanso ntchito ngati zida zamagetsi.
