I-ceramics ye-Sic ayinayo kuphela izakhiwo ezinhle kakhulu zemishini ekamelweni lokushisa, njengamandla aphezulu okugoba, ukumelana ne-oxidation enhle kakhulu, ukumelana nokugqwala okuhle, ukumelana nokugqoka okuphezulu kanye ne-coefficient ephansi ye-friction, kodwa futhi ibe nemishini engcono kakhulu emazingeni okushisa aphezulu (amandla, ukumelana nokukhasa, njll.) phakathi kwezinto ezaziwayo zobumba. I-sintering ecindezelayo eshisayo, i-sintering engacindezeli, izinto zokucindezela ezishisayo ze-isostatic, isici esikhulu kunazo zonke se-silicon carbide amandla okushisa aphezulu, izinto ezijwayelekile ze-ceramic ku-1200 ~ 1400 degrees Celsius amandla azoncishiswa kakhulu, kanye ne-silicon carbide ku-1400 degrees Celsius amandla okugoba. isagcinwe ezingeni eliphakeme lika-500 ~ 600MPa, ngakho izinga lokushisa lokusebenza lingafinyelela ku-1600 degrees Celsius; I-silicon carbide plate texture iqinile futhi i-brittle, i-coefficient yokwandisa incane, ibanda futhi imelana nokushisa, akulula ukuguquguquka. I-silicon carbide iyona encane kakhulu, ngakho izingxenye ze-ceramic ezenziwe nge-silicon carbide zilula kakhulu.
I-Alumina Ceramic iwuhlobo lwe-alumina (Al2O3) njengomzimba oyinhloko we-ceramic material, esetshenziswa kumasekethe ahlanganisiwe efilimu. Ama-ceramics e-alumina ane-conductivity enhle, amandla emishini kanye nokumelana nokushisa okuphezulu. Kumele kuqashelwe ukuthi ukugeza kwe-ultrasonic kuyadingeka. Ukumelana kwayo nokugqoka kuyizikhathi ezingama-266 okwensimbi ye-manganese kanye nezikhathi eziyi-171.5 kune-chromium cast iron ephezulu. I-Alumina Ceramic iwuhlobo lwekhwalithi ephezulu yokuvikela impahla, evame ukusetshenziselwa ukwenza ishidi lokuvikela i-ceramic, indandatho yokuvikela nezinye izingxenye. Izitsha zobumba ze-alumina zingamelana nezinga lokushisa eliphezulu elifika ku-1750℃ (okuqukethwe kwe-alumina okungaphezu kuka-99%).
