Silicon Carbide muaj cov tshuaj lom neeg muaj zog, siab thermal conductivity, qis coefficient ntawm thermal expansion thiab zoo hnav tiv taus. Ntxiv rau kev siv tau ua abrasive, muaj ntau lwm cov kev siv, piv txwv: thaiv cov immeller ntawm hinner tshuab, uas tuaj yeem nce cov kev pabcuam kev ua haujlwm los ntawm 1-2 zaug; Nws yog cov khoom siv hluav taws zoo uas yog qhov cuam tshuam-resistant, me me hauv qhov loj me, lub teeb nyob rau hauv lub zog thiab siab hauv lub zog, thiab muaj lub zog zoo txuag. Low-qib silicon carbide (muaj txog 85% SIC) yog ib qho zoo heev deoxidizing uas tuaj yeem yooj yim rau kev tswj cov tshuaj muaj pes tsawg leeg, thiab txhim kho cov hlau zoo. Tsis tas li ntawd, Silicon Carbide yog dav siv los ua Silicon Carbide Rods rau hluav taws xob cua sov hais.
Silicon carbide muaj kev tawv ncauj heev, nrog mohs hardness ntawm 9.5, thib ob 10), tuaj yeem tawm tsam cov oxidation ntawm cov kub.
Silicon carbide muaj tsawg kawg yog 70 crystalline cov ntaub ntawv. - cua hlob tshaj plaws li 2000 degrees, zoo ib yam li Wurtzite). {{5:}} carricon carbide, uas muaj lub cubic crystal qauv zoo ib yam li pob zeb diamond, cov ntaub ntawv ntawm qhov kub qis dua 2000 degrees. Txawm hais tias thaum siv raws li kev txhawb nqa cataleneous catalentalous kev txhawb nqa, nws yog pom vim muaj qhov chaw ntsiag to tshwj xeeb thiab muaj lub suab nrov tshaj plaws thiab muaj lub suab qab zib ntau dua thaum cuam tshuam.
Vim tias nws cov kev nqus tshwj xeeb ntawm 3.2 g / cm3 thiab siab sublimation kub (txog 2700 tus neeg carric yog heev cov khoom siv rau bearings lossis kub-furnaces. Nws tsis yaj ntawm txhua qhov ua tau zoo thiab muaj cov tshuaj sib xws tsawg. Vim nws lub siab thermal conductivity, loj lawm loj hluav taws xob teb lub zog thiab muaj ntau sim siv nws los hloov cov silicon hauv cov hluav taws xob sawsasonductor. Ib qho ntxiv, nws muaj cov txiaj ntsig microwave muaj zog siv, thiab tag nrho nws cov ntsiab lus siab ua rau nws ua rau nws ua tau rau cov khoom siv kub.
Ntsej muag ntshiab silicon carbide tsis muaj xim, tab sis kev ua lag luam ua rau xim av rau xim dub yog vim cov hlau-muaj impurities. Lub tshuab iridescent ci ntsa iab yog vim muaj kev tiv thaiv txheej ntawm silica uas cov ntaub ntawv ntawm nws qhov chaw.
