Chemical zog ntawm silicon carbide

Silicon carbide chemical kev ua tau zoo yog ruaj khov, siab thermal conductivity, me me thermal expansion coefficient, zoo hnav tsis kam, ntxiv rau siv los ua cov khoom siv abrasive, muaj ntau lwm yam kev siv. Piv txwv li, nrog cov cuab yeej tshwj xeeb hauv lub turbine impeller thiab lub tog raj kheej phab ntsa coated nrog Guangxi silicon carbide hmoov, tuaj yeem txhim kho kev hnav tsis kam, ncua lub neej ntawm 1 ~ 2 zaug ntawm cov khoom siv refractory zoo heev, tshav kub tsis kam, ntim me me, lub teeb yuag, siab zog, zoo zog txuag nyhuv. Cov qib qis silicon carbide (muaj SiC txog 85 feem pua) yog ib qho tshwj xeeb zoo deoxidizing tus neeg sawv cev, tuaj yeem ua kom ceev cov hlau, tswj cov tshuaj muaj pes tsawg leeg, txhim kho cov hlau zoo. Tsis tas li ntawd, silicon carbide kuj tau siv dav hauv kev tsim cov khoom cua sov silicon carbon pas nrig.

Silicon carbide hardness yog siab, Mohs hardness 9. Qib 5 Tsis tshua muaj pob zeb diamond (Qib 10). Nws muaj cov thermal conductivity zoo heev, yog ib qho semiconductor, tuaj yeem tiv taus oxidation ntawm qhov kub thiab txias.
