Silicon carbide (SiC)tau dhau los ua cov khoom siv nrov hauv kev lag luam refractory vim nws cov khoom tshwj xeeb. Nws cov hardness siab, tshuaj tsis kam, thiab thermal stability ua rau nws cov khoom zoo heev rau kev sib tsoo daim ntaub ntawv. Silicon carbide yog tsim los siv cov txheej txheem kub-kub, uas ua rau cov qauv crystalline uas ua rau nws yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws hauv ntiaj teb.
Hauv kev lag luam sib tsoo, SiC yog siv rau ntau yam kev siv, suav nrog kev txiav, sib tsoo, thiab ua tiav cov hlau, ceramics, thiab lwm yam ntaub ntawv. Kev siv SiC hauv kev lag luam refractory tau nce ntau hauv xyoo tas los no, vim nws muaj peev xwm tiv taus qhov kub thiab txias. Silicon carbide tseem paub txog nws cov thermal conductivity, uas tso cai rau nws kom dissipate tshav kub sai sai thaum lub sij hawm sib tsoo txheej txheem, txo qhov kev pheej hmoo ntawm thermal puas rau lub workpiece.
Kev siv SiC hauv kev lag luam refractory tau hloov pauv txoj kev sib tsoo los ntawm kev tsim cov cuab yeej sib tsoo siab heev. Silicon carbide abrasives yog siv nyob rau hauv kev tsim kho ntawm kev sib tsoo log, siv, thiab discs. Kev siv SiC abrasives tau ua rau muaj kev nce ntxiv hauv kev sib tsoo thiab qhov zoo ntawm cov khoom kawg.
Ib qho txiaj ntsig tseem ceeb ntawm SiC hauv kev lag luam refractory yog nws cov kav ntev. Silicon carbide muaj qhov tsis kam hnav thiab tsim kua muag, ua rau nws yog ib qho khoom siv zoo rau kev sib tsoo daim ntaub ntawv. Nws kuj yog resistant rau tshuaj corrosion, uas ua rau nws zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig.
Silicon carbide tau ua pov thawj los ua ib qho kev ua si-hloov hauv kev sib tsoo kev lag luam, txo tus nqi sib tsoo thaum nce kev tsim khoom. Kev siv SiC abrasives hauv cov cuab yeej sib tsoo tau tso cai rau kev tsim cov cuab yeej sib tsoo zoo dua thiab ruaj khov. Qhov no tau ua rau muaj kev nce hauv qhov zoo ntawm cov khoom kawg thiab txo tus nqi ntawm kev tsim khoom.
Kev siv SiC abrasives kuj tau ua rau txo qis kev cuam tshuam ib puag ncig ntawm kev sib tsoo. Silicon carbide yog ib yam khoom uas tshwm sim uas tuaj yeem rov ua dua tshiab, txo cov khib nyiab thiab txo qhov xav tau ntawm cov khoom siv tshiab. Silicon carbide kuj yog cov khoom siv tsis zoo uas tsis tso cov pa phem lossis cov khoom siv thaum lub sijhawm sib tsoo.
