Tshwj xeeb lub hardness & kho tshuab zog
Mohs hardness ntawm ~ 9.5, thib ob tsuas yog pob zeb diamond thiab boron nitride.
SiabHnav Tsis kam, ua rau nws zoo tagnrho rau cov ntawv thov abrivas (piv txwv li, cov log sib tsoo, cov cuab yeej txiav).
Saib xyuas cov neeg kho tshuab ruaj khov txawm tias muaj kev ntxhov siab heev.
Dav Bandgap Semiconductor Cov Khoom Muaj
Bandgap ntawm 3.26 EV (4H-SIC), Loj dua li silicon (1.12 ev).
Ua haujlwm ntawmntau dua volfages, kub, thiab ntau zaus.
Txo lub zog poob hauv cov khoom hluav taws xob fais fab.
SiabHluav taws xob teb lub zog(10 x uas ntawm silicon), tso cai rau thinner, ntau cov cuab yeej tsim tau zoo.
Zoo kawg cua yam khoom
Siab high thermal conductivity (~ 490 w / min rau 4H-siic ntawm chav tsev kub), surpassing feem ntau cov hlau thiab semiconductors.
Zoo tshajThaum tshav sov tsis kam, qhov tseem ceeb rau lub hwj huam hluav taws xob thiab cov khoom siv high-zaus.
Thermal Stability txog 1,600 degree(Melting taw tes ~ 2,700 degree), haum rau cov cheeb tsam heev (piv txwv li, aerospace, nuclear reactors).
