SiC khoom nta
Kub kub thiab corrosion resistant, txhim kho wafer zoo thiab productivity
SiC hais txog silicon carbide. Silicon carbide (SiC) yog ua los ntawm quartz xuab zeb, coke thiab lwm yam raw cov ntaub ntawv los ntawm kub kub rauv melting. Kev lag luam tam sim no ntawm silicon carbide muaj ob hom, dub silicon carbide thiab ntsuab silicon carbide. Ob leeg yog hexagonal siv lead ua, lub ntiajteb txawj nqus ntawm 3.21g / cm3, micro hardness ntawm 2840 ~ 3320kg / mm2.
Yam tsawg kawg yog 70 hom crystalline silicon carbide, vim nws tsis tshua muaj lub ntiajteb txawj nqus 3.21g / cm3 thiab kub lub zog, nws yog haum rau bearings los yog kub kub rauv raw cov ntaub ntawv. ntawm txhua qhov siab tsis tuaj yeem ncav cuag, thiab muaj cov tshuaj lom neeg tsawg heev.
Nyob rau tib lub sijhawm, ntau tus neeg tau sim hloov silicon nrog silicon carbide vim lawv cov thermal conductivity siab, siab crush hluav taws xob lub zog thiab siab tshaj plaws tam sim no ceev. Tsis ntev los no, nyob rau hauv daim ntawv thov ntawm semiconductor siab zog Cheebtsam. Qhov tseeb, silicon carbide substrate nyob rau hauv thermal conductivity, ntau tshaj 10 lub sij hawm siab tshaj sapphire substrate, yog li kev siv ntawm silicon carbide substrate LED Cheebtsam, nrog zoo conductivity thiab thermal conductivity, kuj conducive rau zus tau tej cov high-power LED.
