Silicon carbide muaj ntau yam tshuaj lom neeg zoo, suav nrog cov thermal conductivity, qis coefficient ntawm thermal expansion thiab zoo hnav tsis kam. Ntxiv rau nws siv los ua ib qho abrasive, silicon carbide muaj ntau yam kev siv. Piv txwv li, silicon carbide hmoov yog siv rau turbine impellers lossis cylinder blocks siv cov txheej txheem tshwj xeeb. Sab hauv phab ntsa tuaj yeem kav ntev li ob zaug thiab hnav-tiv taus.
Nws cov khoom siv refractory siab heev yog tiv taus thermal shocks, me me, lub teeb hauv qhov hnyav, siab zog thiab muaj txiaj ntsig zoo rau kev txuag hluav taws xob. Qib qis silicon carbide (muaj txog 85% SiC) yog ib qho zoo heev deoxidiser. Nws tuaj yeem txhim kho cov txheej txheem steelmaking, xyuas kom meej tswj cov tshuaj muaj pes tsawg leeg thiab txhim kho steel zoo. Tsis tas li ntawd, silicon carbide yog cov khoom siv tseem ceeb hauv kev tsim cov silicon carbide rods rau hluav taws xob cua sov. Silicon carbide yog cov khoom siv muaj zog nrog lub hardness ntawm 9.5 ntawm Mohs nplai, uas tso nws thib ob rau pob zeb diamond (theem 10) ntawm Mohs hardness nplai. Nws muaj cov thermal conductivity zoo heev, cov khoom siv hluav taws xob semiconducting thiab tsis kam mus rau high-kub oxidation.
