Txog Silicon Carbide thiab Sic Ceramics

Silicon carbide tau ua kom zoo heev rau corrosion, muaj zog dua, thiab zoo dua thermal poob siab tshaj Alumincell Namet kub heev. Silicon carbide yog tsim los ntawm tetrahedra ntawm cov pa roj carbon thiab silicon atoms nrog cov khoom sib txuam muaj zog hauv cov tawv ntoo. Qhov no tsim cov khoom siv nyuaj thiab muaj zog. Silicon carbide tsis tau tawm tsam los ntawm ib qho kua qaub lossis alkalis lossis cov ntsev ua kom ntev li ntawm 800ºC. Nyob rau hauv huab cua, sic ua cov cua tiv thaiv silicon oxide txheej ntawm 1200ºC thiab muaj peev xwm siv tau rau 1600ºC. Lub siab thermal condled txuas nrog tsawg thermal exporsion thiab siab lub zog muab cov ntaub ntawv no tsuas yog tiv thaiv zoo. Silicon carbide ceramics nrog me me lossis tsis muaj qoob loo conrary tswj lawv lub zog rau qhov kub siab heev, nce 1600ºC nrog tsis muaj zog ploj. Tshuaj lom neeg purity, tiv thaiv kev tshuaj tua rog ntawm qhov kub thiab txias tau ua cov khoom siv hluav taws xob ntau li wafer tais txhawb nqa thiab paddles hauv cov chaw ua kom sov. THCELL NAMELECTRICAL COLDITTING NTAWM cov khoom tau ua rau nws siv rau cov khoom siv cua sov (thiab ua cov hluav taws xob tiv thaiv hluav taws xob) thiab hauv varistors (ntsuas hluav taws xob tiv thaiv). Lwm yam kev siv suav nrog lub ntsej muag ntsej muag, hnav daim hlau, bearings thiab liner leeg.
