Cov xim yog dawb, qhov loj me yog qhov tseeb, yooj yim rau kev txiav thiab nruab, kev tsim kho yooj yim, thiab tus txiv neej-teev tau txais kev cawmdim
Nws tsis muaj cov binders thiab tuaj yeem siv tau ntev hauv qhov nruab nrab, oxidizing cua
Tsawg tshav kub muaj peev xwm, tsawg thermal conductivity, siab refractory thiab siab kub rhiab heev
Zoo heev cua erosion kuj thiab mechanical impact resistance
Zoo heev suab absorption thiab tua hluav taws
Tsis siv neeg ntau lawm, ruaj khov ceev thiab kev ua tau zoo
