Sic ceramics haina chete hunhu hwakanaka hwemakanika patembiricha yemumba, senge simba rekukotama rakakwira, resistance yakanaka yeoxidation, resistance yakanaka yengura, resistance yakanyanya kupfeka uye low friction coefficient, asiwo ine hunhu hwakanaka hwemakanika patembiricha yepamusoro (simba, resistance inokambaira, nezvimwewo) pakati pezvinhu zveceramic zvinozivikanwa. Hot pressing sintering, non-pressing sintering, hot isostatic pressing sintering materials, hunhu hukuru hwesilicon carbide isimba rekupisa rakakwira, zvinhu zveceramic zvakajairika pa1200 ~ 1400 degrees Celsius simba richaderedzwa zvakanyanya, uye silicon carbide pa1400 degrees Celsius bend strength ichiri kuchengetwa padanho repamusoro re500 ~ 600MPa, saka tembiricha yekushanda inogona kusvika 1600 degrees Celsius; Silicon carbide plate texture yakaoma uye inopfava, expansion coefficient idiki, inotonhora uye inopisa resistance, haisi nyore kuchinja. Silicon carbide ndiyo ine dense shoma, saka zvikamu zveceramic zvakagadzirwa nesilicon carbide zvakapusa.
Alumina ceramic rudzi rwealumina (Al2O3) sechikamu chikuru chezvinhu zveceramic, zvinoshandiswa muma circuits akakora akabatanidzwa. Alumina ceramics ine conductivity yakanaka, simba remakanika uye inodzivirira kupisa kwakanyanya. Zvinofanira kucherechedzwa kuti kushambidzwa kwe ultrasonic kunodiwa. Inodzivirira kupera kwayo ka266 kupfuura simbi ye manganese uye ka171.5 kupfuura simbi ine chromium yakawanda. Alumina ceramic rudzi rwezvinhu zvekudzivirira kupisa zvemhando yepamusoro, izvo zvinowanzoshandiswa kugadzira jira rekudzivirira kupisa re ceramic, rin'i yekudzivirira kupisa nezvimwe zvikamu. Alumina ceramics inogona kutsungirira kupisa kwakanyanya kusvika 1750℃ (huwandu hwealumina hunopfuura 99%).
