I-ceramics ye-Sic ayinayo kuphela iimpawu ezigqwesileyo zoomatshini kwiqondo lobushushu begumbi, njengamandla okugoba okuphezulu, ukuxhathisa okugqwesileyo kwe-oxidation, ukuxhathisa okulungileyo kokugqwala, ukumelana nokunxiba okuphezulu kunye ne-coefficient ephantsi yokukhuhlana, kodwa kwakhona zineempawu ezingcono kakhulu zoomatshini kubushushu obuphezulu (amandla, ukuxhathisa ukukhasa, njl. njl.) phakathi kwezinto ezaziwayo ze-ceramic. Ukucofa ukucofa okushushu, ukucofa okungacinezeliyo, ukucofa kwe-isostatic kwezixhobo zokucofa, olona phawu lubalaseleyo lwesilicon carbide ngamandla obushushu obuphezulu, imathiriyeli ye-ceramic eqhelekileyo kwi-1200 ~ 1400 degrees Celsius amandla aya kuncitshiswa kakhulu, kunye ne-silicon carbide kwi-1400 degrees Celsius amandla okugoba asagcinwe kwinqanaba eliphezulu le-500MPa ukuya kwi-60 ℃ ukuya kufikelela kwiqondo lobushushu le-Celsius eyi-500, ukuya kuthi ga kwi-60. I-silicon ye-carbide plate texture ilukhuni kwaye i-brittle, i-coefficient yokwandisa incinci, ibanda kunye nokumelana nokushisa, akukho lula ukuguqulwa. I-silicon carbide yeyona nto ixineneyo, ngoko ke iindawo ze-ceramic ezenziwe nge-silicon carbide zezona zilula.
I-alumina ceramic luhlobo lwe-alumina (Al2O3) njengomzimba oyintloko wemathiriyeli ye-ceramic, esetyenziswa kwiisekethe ezishinyeneyo ezidityanisiweyo zefilimu. I-alumina ceramics ine-conductivity enhle, amandla omatshini kunye nokumelana nokushisa okuphezulu. Kufuneka kuqatshelwe ukuba ukuhlamba i-ultrasonic kuyadingeka. Ukumelana kwayo nokunxiba ngamaxesha angama-266 okwentsimbi ye-manganese kunye namaxesha angama-171.5 entsimbi ye-chromium ephezulu. I-alumina ceramic luhlobo lwemathiriyeli ekumgangatho ophezulu yokugquma, ehlala isetyenziselwa ukwenza i-ceramic insulating sheet, i-insulating ring kunye nezinye iindawo. Iiseramikhi zealumina ziyakwazi ukumelana nobushushu obuphezulu ukuya kuthi ga kwi-1750℃ (umxholo we-alumina ngaphezu kwe-99%).
