Alumina ceramic imhando yealuminium (Al2O3) seyakanyanya ceramic zvinhu, inoshandiswa mune gobvu firimu rakasanganiswa redunhu.Alumina ceramics ine yakanaka conductivity, mechanical simba uye yakakwirira tembiricha kuramba.
Alumina ceramics ikozvino yakakamurwa kuva marudzi maviri: yakakwirira kuchena uye yakajairika.Yakakwirira kuchena alumina ceramic inodarika 99.9% Al2O3 zvirimo zveceramic zvinhu, nekuda kwekupisa kwayo kupisa kusvika 1650-1990 ℃, transmission wavelength ye1 ~ 6μm, inowanzogadzirwa negirazi yakanyungudutswa kutsiva iyo platinamu crucible.Nekuda kwemwenje wayo wekufambisa uye kuramba kune alkali simbi corrosion, inogona kushandiswa sesodium rambi chubhu, muindasitiri yemagetsi inogona kushandiswawo seyakabatanidzwa redunhu bhodhi uye yakakwirira frequency insulation zvinhu.
Yakajairwa alumina ceramics yakakamurwa kuita 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain uye mamwe marudzi zvinoenderana neAl2O3 zvemukati, dzimwe nguva Al2O3 zvirimo mu80% kana 75% zvakare inoonekwa seyakajairwa alumina ceramic mutsara.Pakati pazvo, 99 alumina ceramic zvinhu zvinoshandiswa kugadzira tembiricha yakakwira crucible, chubhu yechoto uye yakakosha kusapfeka zvinhu, senge ceramic bearings, ceramic seals nemavharuvhu emvura, etc. zvikamu;85 alumina ceramic material inowanzosanganiswa nechikamu chetalc, inovandudza zvinhu zvemagetsi uye simba remagetsi, uye inogona kuiswa chisimbiso ne molybdenum, niobium, tantalum nedzimwe simbi, dzimwe dzinoshandiswawo semagetsi emagetsi.
