Iiseramikhi zeSic azinazo nje kuphela iimpawu ezibalaseleyo zoomatshini kubushushu begumbi, ezinje ngamandla aphezulu okugoba, ukumelana okuhle kwe-oxidation, ukumelana okuhle nokugqwala, ukumelana okuphezulu kokuguguleka kunye ne-coefficient ephantsi yokungqubana, kodwa zikwanazo neempawu ezibalaseleyo zoomatshini kubushushu obuphezulu (amandla, ukumelana nokuqhekeka, njl.njl.) phakathi kwezinto zeseramikhi ezaziwayo. Ukutshiza okushushu, ukutshiza okungacinezeliyo, izixhobo zokutshiza ezishushu ezi-isostatic, uphawu olukhulu lwe-silicon carbide ngamandla aphezulu obushushu, izixhobo zeseramikhi eziqhelekileyo kwi-1200 ~ 1400 degrees Celsius amandla aya kuncitshiswa kakhulu, kwaye i-silicon carbide kwi-1400 degrees Celsius amandla okugoba asagcinwa kwinqanaba eliphezulu le-500 ~ 600MPa, ngoko ke ubushushu bokusebenza bunokufikelela kwi-1600 degrees Celsius; Ubume beplate ye-silicon carbide buqinile kwaye bubuthathaka, i-coefficient yokwandiswa incinci, ukumelana nokubanda nobushushu, akukho lula ukuyiguqula. I-Silicon carbide yeyona incinci kakhulu, ngoko ke iindawo zeseramikhi ezenziwe nge-silicon carbide zikhaphukhaphu.
I-Alumina ceramic luhlobo lwe-alumina (Al2O3) njengomzimba oyintloko wezinto ze-ceramic, ezisetyenziswa kwiisekethe ezidityanisiweyo zefilimu etyebileyo. Ii-Alumina ceramics zinomoya oqhuba kakuhle, amandla oomatshini kunye nokumelana nobushushu obuphezulu. Kufuneka kuqatshelwe ukuba kufuneka ukuhlamba nge-ultrasonic. Ukumelana kwayo nokuguguleka kuphindwe ka-266 kunentsimbi ye-manganese kunye ne-171.5 kunentsimbi ephezulu ye-chromium. I-Alumina ceramic luhlobo lwezinto zokukhusela ezikumgangatho ophezulu, ezisetyenziswa rhoqo ukwenza iphepha lokukhusela le-ceramic, indandatho yokukhusela kunye nezinye iindawo. Ii-Alumina ceramics zinokumelana nobushushu obuphezulu ukuya kuthi ga kwi-1750℃ (umxholo we-alumina ungaphezulu kwe-99%).
