cov qauv thiab nta ntawm silicon carbide
Silicon carbide belongs rau IV-IV pawg ntawm cov tebchaw, nrog cov tshuaj formula SiC, uas yog tsim los ntawm covalent bonding ntawm silicon thiab carbon. Muaj peb lub ntsiab ntawm cov qauv siv lead ua, xws li -SiC ntawm lub cubic siv lead ua, -SiC ntawm hexagonal siv lead ua system thiab 6H-SiC ntawm rhombic siv lead ua. Qhov ceev, qhov sib txawv band thiab lwm yam khoom ntawm peb hom no txawv.
Cov khoom tseem ceeb ntawm silicon carbide yog siab hardness, siab modulus, siab toughness thiab zoo heev kub-kub oxidation kuj. Nws hardness yog thib ob tsuas yog pob zeb diamond, thiab nws cov qauv yog li ob npaug ntawm pob zeb diamond. Qhov no feem ntau yog vim muaj kev sib koom ua ke zoo heev ntawm SiC nws tus kheej. Tsis tas li ntawd, silicon carbide muaj cov coefficient tsawg ntawm thermal expansion, thermal conductivity zoo, thiab siab thermal shock damping. Txawm tias qhov kub ntawm 1000 degree, SiC khaws cov khoom siv zoo, uas ua rau nws muaj txiaj ntsig zoo rau cov khoom kub kub.
daim ntawv thov teb ntawm silicon carbide
Raws li cov khoom siv ntau yam, silicon carbide plays qhov tshwj xeeb kom zoo dua hauv ntau qhov chaw, tsav tsheb tshiab thiab kev loj hlob hauv ntau qhov chaw.
Electronics & Semiconductors:Hauv kev lag luam electronics thiab semiconductor, silicon carbide tau tshwm sim los ua lwm txoj hauv kev ua silicon. Nws cov thermal conductivity thiab kev kub siab ua haujlwm ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv hluav taws xob uas ua haujlwm ntawm lub zog siab, siab zaus, thiab kub siab. Los ntawm lub zog amplifiers mus rau RF keyboards, silicon carbide pab txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Piv txwv:High-voltage thyristors (IGBTs) yog cov khoom siv hluav taws xob siv hluav taws xob ntau, thiab silicon carbide tuaj yeem siv los tsim cov kev ua haujlwm siab-voltage IGBTs rau kev hloov hluav taws xob ntau dua.
Piv txwv:Nyob rau hauv cov roj turbine xyaw, silicon carbide hniav tuaj yeem tiv taus qhov kub thiab txias siab, muab kev sib txuas ntau dua thiab cov khoom siv hluav taws xob.
Cov khoom siv ceramic:Lub siab tawv thiab hnav tsis kam ntawm silicon carbide ua rau nws muaj peev xwm zoo hauv kev tsim cov cuab yeej ceramic, abrasives, thiab ceramic bearings. Cov ntawv thov no xav tau cov ntaub ntawv nrog kev hnav zoo heev thiab kev tiv thaiv corrosion.
Piv txwv:Thaum tsim cov riam ceramic, silicon carbide hniav muaj kev ua haujlwm zoo heev thiab tuaj yeem siv rau kev txiav zoo thiab txiav cov ntaub ntawv siab hardness.
Txheej technology:Silicon carbide coatings tuaj yeem siv los muab kev hnav-tiv taus, corrosion-resistant nto tiv thaiv rau aviation, tsheb, tshuaj thiab lwm yam kev siv. Cov coatings no tiv thaiv cov khoom siv substrate los ntawm kev puas tsuaj rau sab nraud thiab lub cev.
Piv txwv:Hauv kev lag luam aerospace, silicon carbide txheej tuaj yeem siv rau ntawm qhov chaw dav hlau los muab kev tiv thaiv thiab txuas ntxiv kev pab cuam lub neej.
