1. Dab tsi yog silicon carbide?
Silicon carbide (SiC) yog cov khoom sib xyaw ua ke ntawm cov pa roj carbon thiab silicon, feem ntau yog cov xim dub lossis ntsuab. Nws yog cov khoom siv tawv heev nrog lub siab melting point, zoo heev thermal conductivity thiab tshuaj tiv thaiv, yog li nws yog dav siv nyob rau hauv kev sib tsoo, txiav, hluav taws xob cov cuab yeej thiab cov khoom siv kub.
2. Dab tsi yog cov ntawv thov tseem ceeb ntawm silicon carbide?
Abrasive cov ntaub ntawv: siv los ua kev sib tsoo log, sandpaper, abrasives, thiab lwm yam.
Cov khoom siv semiconductor: siv los ua kom muaj qhov kub thiab txias, muaj zog thiab muaj zog hluav taws xob xws li diodes, MOSFETs, thiab lwm yam.
Cov ntaub ntawv refractory: siv nyob rau hauv qhov kub thiab txias ib puag ncig xws li kub kub kilns thiab tshav kub exchangers.
Mechanical seals: siv rau kev sib khi cov khoom hauv cov cuab yeej siv tshuab xws li twj thiab compressors.
Cov khoom siv ceramic: siv los ua ntau yam hnav-resistant thiab corrosion-resistant ceramic khoom.
3. Dab tsi ntawm silicon carbide muaj?
Dub silicon carbide: muaj cov pa roj carbon ntau dua thiab siab hardness, thiab feem ntau yog siv rau cov khoom sib tsoo.
Ntsuab silicon carbide: muaj purity ntau dua thiab hardness dua, thiab yog siv los txiav cov ntaub ntawv nyuaj.
Reaction-bonded silicon carbide (RBSiC): Ua los ntawm cov txheej txheem sintering, nws muaj cov khoom siv zoo heev thiab kev tiv thaiv corrosion.
Kub-pressed sintered silicon carbide (HPSiC): Ua los ntawm cov txheej txheem kub-nias sintering, nws muaj ntau dua ntom ntom thiab txhua yam muaj zog.
4. Dab tsi yog txoj kev npaj ntawm silicon carbide?
Cov txheej txheem ib txwm: Ua los ntawm cua sov sib tov ntawm quartz xuab zeb thiab roj av coke kom kub kub hauv qhov cub tsis kam.
Vapor deposition method (CVD): Depositing silicon carbide film on a substrate by chemical vapor deposition technology.
Sintering txoj kev: suav nrog cov tshuaj tiv thaiv sintering, kub nias sintering, thiab lwm yam, los ntawm nias silicon carbide hmoov rau hauv cov duab thiab sintering ntawm qhov kub thiab txias.
5. Dab tsi yog qhov zoo ntawm silicon carbide nyob rau hauv semiconductor teb?
Siab tawg hluav taws xob lub zog: tso cai rau kev siv hluav taws xob ntau dua.
High thermal conductivity: Cov cua kub zoo, haum rau cov khoom siv hluav taws xob siab.
High electron mobility: Txhim kho qhov hloov ceev ntawm lub cuab yeej.
Wide bandgap: tseem tuaj yeem tswj tau cov khoom siv hluav taws xob zoo heev ntawm qhov kub thiab txias.
