Silicon carbide, tseem hu ua SiC, yog cov khoom siv semiconductor uas muaj cov ntshiab silicon thiab cov pa roj carbon ntshiab. Koj tuaj yeem dope SiC nrog nitrogen lossis phosphorus los ua ib hom n-hom semiconductor lossis dope nrog beryllium, boron, aluminium, lossis gallium los tsim p-hom semiconductor. Txawm hais tias muaj ntau yam thiab purities ntawm silicon carbide, semiconductor-qib zoo silicon carbide tsuas yog tshwm sim rau kev siv nyob rau hauv ob peb lub xyoo dhau los.
Qhov zoo ntawm Silicon Carbide
Keeb kwm, manufacturers siv silicon carbide nyob rau hauv high-temperature chaw rau cov cuab yeej xws li bearings, cua sov machinery Cheebtsam, tsheb nres, thiab txawm riam sharpening cuab yeej. Hauv kev siv hluav taws xob thiab khoom siv hluav taws xob, SiC qhov txiaj ntsig tseem ceeb yog:
High thermal conductivity ntawm 120-270 W/mK
Tsawg coefficient ntawm thermal expansion ntawm 4.0x10^-6/degree
Qhov siab tshaj plaws tam sim no ceev
Peb cov yam ntxwv no ua ke muab SiC zoo tshaj plaws hluav taws xob conductivity, tshwj xeeb tshaj yog thaum piv rau silicon, SiC cov kwv tij nrov tshaj. SiC cov yam ntxwv ntawm cov khoom ua rau nws muaj txiaj ntsig zoo rau kev siv hluav taws xob siab uas yuav tsum muaj tam sim no, kub kub, thiab thermal conductivity siab.
Nyob rau hauv xyoo tas los no, SiC tau dhau los ua tus neeg tseem ceeb hauv kev lag luam semiconductor, siv lub zog MOSFETs, Schottky diodes, thiab fais fab modules siv rau hauv high-power, high-efficiency applications. Thaum kim dua silicon MOSFETs, uas feem ntau txwv rau kev tawg voltages ntawm 900V, SiC tso cai rau qhov ntsuas hluav taws xob ze li ntawm 10kV.
SiC kuj tseem muaj qhov kev poob qis heev thiab tuaj yeem txhawb kev ua haujlwm siab zaus, uas tso cai rau nws kom ua tiav cov txiaj ntsig tsis muaj txiaj ntsig tam sim no, tshwj xeeb tshaj yog hauv cov ntawv thov uas ua haujlwm ntawm ntau dua 600 volts. Nrog rau kev siv kom raug, SiC cov cuab yeej tuaj yeem txo qhov kev hloov pauv thiab lub zog inverter poob los ntawm ze li ntawm 50%, qhov loj los ntawm 300%, thiab tag nrho cov nqi hluav taws xob los ntawm 20%. Qhov kev txo qis hauv tag nrho qhov system loj qiv SiC muaj peev xwm ua tau zoo heev hauv qhov hnyav thiab qhov chaw-sensitive daim ntaub ntawv.
Kev siv ntawm Silicon carbide
Ua tsaug rau nws cov khoom siv ntau yam, silicon carbide yog cov khoom siv dav siv hauv cov khoom siv hauv ntau qhov kub thiab txias thiab hnav-tiv taus, xws li:
Cov ntawv thov refractory hauv kev tsim cov hlau, hlau, ceramics, nonferrous hlau, zog, tshuaj, thiab lwm yam.
Lub tshuab hluav taws xob kub kub hauv cov khoom siv hauv kev tsim tshuaj lom neeg thiab hauv turbine lossis lub cav kuaj kom pom cov pa taws kub hnyiab thiab kub hnyiab tau hauv qhov hnyav, kub kub, thiab corrosive ib puag ncig
Ceramic welding hmoov
Semiconductors nyob rau hauv cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob ua tsaug rau nws qhov kev ua haujlwm siab-voltage
