SiC muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, xws li lub siab melting point, siab hardness, corrosion kuj thiab oxidation kuj. Tshwj xeeb tshaj yog nyob rau hauv thaj tsam ntawm 1800-2000 ℃, SiC muaj kev ua haujlwm zoo ablation. Yog li ntawd, nws muaj kev thov dav dav hauv aerospace, khoom siv riam phom thiab lwm yam haujlwm. Txawm li cas los xij, SiC nws tus kheej tsis tuaj yeem siv los uaib tug qauvkhoom siv,yog li cov txheej txheem txheej feem ntau yog siv los ua kev siv nws cov hnav tsis kam thiab ablation resistance.
Silicon carbide(SIC) cov khoom siv semiconductor yog peb tiam seCov khoom siv microductor tsim tom qab thawj tiam cov khoom siv semiconductor (Si, GE) thiab cov khoom siv hluav taws xob thib ob (GaAs, qhov sib txawv, InP, thiab lwm yam). Raws li cov khoom siv dav dav ntawm cov khoom siv semiconductor, silicon carbide muaj cov yam ntxwv ntawm qhov sib txawv loj ntawm qhov dav, siab tawg teb lub zog, siab thermal conductivity, siab cab kuj saturation drift ceev, me me dielectric tas li, muaj zog hluav taws xob tsis kam thiab zoo tshuaj stability. Nws tuaj yeem siv los tsim ntau yam khoom siv hluav taws xob ntau zaus thiab lub zog muaj zog nrog qhov kub thiab txias thiab tuaj yeem siv rau lub sijhawm uas cov khoom siv silicon tsis muaj peev xwm, Los yog tsim cov nyhuv uas cov khoom siv silicon nyuaj rau tsim hauv kev siv dav dav.
Daim ntawv thov tseem ceeb: siv rau kev txiav hlau ntawm 3-12 nti monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz siv lead ua, thiab lwm yam.Siv hauvsemiconductor, xob laim pas nrig, Circuit Court caij, daim ntawv thov kub, ultraviolet detector, structural khoom, astronomy, disc nres, clutch, diesel particulate lim, filament pyrometer, ceramic zaj duab xis, tej cuab yeej, cua sov caij, nuclear roj, hniav nyiaj hniav kub, hlau, khoom tiv thaiv, catalyst kev them nyiaj yug thiab lwm yam teb
