I-alumina ceramic luhlobo lwe-alumina (Al2O3) njengeyona nto ingundoqo ye-ceramic, esetyenziswa kwifilimu eshinyeneyo edityanisiweyo yesekethe.I-alumina ceramics ine-conductivity enhle, amandla omatshini kunye nokumelana nokushisa okuphezulu.
Iiseramics ze-alumina okwangoku zahlulwe zibe ziindidi ezimbini: ukucoceka okuphezulu kunye nokuqhelekileyo.Ucoceko oluphezulu lwe-alumina ceramic lungaphezulu kwe-99.9% ye-Al2O3 yomxholo wezinto ze-ceramic, ngenxa yobushushu bayo be-sintering ukuya kwi-1650-1990℃, ubude be-wavelength ye-1 ~ 6μm, ngokubanzi yenziwe ngeglasi etyhidiweyo ukuze ithathe indawo ye-crucible platinum.Ngenxa yokuhambisa ukukhanya kunye nokuchasana nokubola kwesinyithi, inokusetyenziswa njengetyhubhu yesibane sesodium, kumzi mveliso we-elektroniki unokusetyenziswa njengebhodi yesekethe edibeneyo kunye nemathiriyeli ephezulu yokugquma.
Iiseramikhi eziqhelekileyo ze-alumina zahlulwe zibe yi-99 porcelain, i-porcelain engama-95, i-porcelain engama-90, i-porcelain engama-85 kunye nezinye iindidi ngokomxholo we-Al2O3, ngamanye amaxesha umxholo we-Al2O3 kwi-80% okanye i-75% nayo ithathwa njengesiqhelo se-alumina ceramic series.Phakathi kwazo, izixhobo ze-alumina ze-alumina ze-99 zisetyenziselwa ukwenza i-crucible yobushushu obuphezulu, ityhubhu yesithando somlilo kunye nezixhobo ezikhethekileyo zokunxiba, ezifana neebheringi ze-ceramic, izitywina ze-ceramic kunye neevalvu zamanzi, njl njl. Izinto ze-alumina ze-95 ze-alumina ze-ceramic zisetyenziswa ikakhulu njenge-corrosion resistant, i-resistant corrosion. amalungu;Izinto ze-alumina ze-alumina ze-85 ze-ceramic zihlala zixutywa kunye nenxalenye ye-talc, ziphucula iipropati zombane kunye namandla omatshini, kwaye zinokutywinwa nge-molybdenum, i-niobium, i-tantalum kunye nezinye izinyithi, ezinye zisetyenziswa njengezixhobo zombane zokucoca.
