Silicon carbide yog hom tshiab ntawm ceramics nrog cov nqi siab thiab cov khoom siv zoo heev. Vim muaj cov yam ntxwv zoo li lub zog siab thiab hardness, kub tsis kam, thermal conductivity thiab tshuaj corrosion kuj, Silicon Carbide yuav luag txhua yam tshuaj nruab nrab. Yog li ntawd, SiC tau siv dav hauv kev lag luam roj, tshuaj lom neeg, tshuab thiab airspace, txawm tias lub zog nuclear thiab cov tub rog muaj lawv qhov tshwj xeeb xav tau ntawm SIC. Qee daim ntawv thov ib txwm peb tuaj yeem muab yog lub nplhaib foob rau lub twj tso kua mis, lub valve thiab cov cuab yeej tiv thaiv thiab lwm yam.
Peb tuaj yeem tsim thiab tsim khoom raws li koj qhov tshwj xeeb qhov ntev nrog cov khoom zoo thiab tsim nyog lub sijhawm.
