Li-ceramics tsa Sic ha li na lisebelisoa tse ntle feela tsa mochini mocheso oa kamore, joalo ka matla a holimo a ho kobeha, ho hanyetsa oxidation e ntle, ho hanyetsa kutu, khanyetso e phahameng ea ho roala le coefficient e tlase ea likhohlano, empa hape e na le thepa e ntle ka ho fetisisa ea mochini mochesong o phahameng (matla, khanyetso ea creep), joalo-joalo) har'a lisebelisoa tse tsebahalang tsa ceramic. Sintering e chesang e chesang, e sa hatelleng, lisebelisoa tse chesang tsa isostatic pressing sintering, tšobotsi e kholo ka ho fetisisa ea silicon carbide ke matla a mocheso o phahameng, lisebelisoa tse tloaelehileng tsa ceramic ka 1200 ~ 1400 degrees Celsius matla a tla fokotsoa haholo, 'me silicon carbide ka 1400 degrees Celsius matla a ho kobeha. e ntse e bolokiloe boemong bo phahameng ba 500 ~ 600MPa, kahoo mocheso o sebetsang o ka fihla likhato tse 1600 tsa Celsius; Silicon carbide plate texture e thata ebile e brittle, coefficient ea katoloso e nyane, e bata ebile e chesa, ha ho bonolo ho e fetola. Silicon carbide ke eona e teteaneng haholo, kahoo likarolo tsa ceramic tse entsoeng ka silicon carbide ke tsona tse bobebe ka ho fetisisa.
Alumina ceramic ke mofuta oa alumina (Al2O3) e le 'mele o ka sehloohong oa thepa ea ceramic, e sebelisoang lipotolohong tse teteaneng tsa filimi. Li-ceramics tsa aluminium li na le conductivity e ntle, matla a mochine le ho hanyetsa mocheso o phahameng. Hoa lokela ho hlokomeloa hore ho hlatsoa ha ultrasonic hoa hlokahala. Ho hanyetsa ha eona ke makhetlo a 266 a tšepe ea manganese le makhetlo a 171.5 a tšepe e phahameng ea chromium. Alumina ceramic ke mofuta oa thepa ea boleng bo phahameng ea insulating, eo hangata e sebelisetsoang ho etsa letlapa le sireletsang ceramic, selikalikoe sa insulating le likarolo tse ling. Alumina ceramics e ka mamella mocheso o phahameng ho fihla ho 1750 ℃ (liteng tsa aluminium tse fetang 99%).
