Dab tsi yog Green Silicon Carbide

Green Silicon Carbide yog dab tsi?

Silicon carbideyog ib tug compound ua los ntawm carbon thiab silicon atoms. Nws yog cov khoom siv lead ua uas feem ntau muaj qhov nyuaj ntawm 9 ntawm Mohs nplai. Qhov no ua rau nws yog ib qho khoom siv nyuaj tshaj plaws hauv ntiaj teb. Silicon carbide yog siv rau hauv ntau daim ntawv thov kev lag luam, xws li cov hmoov abrasive thiab cov ntaub ntawv txiav.

Ntsuab silicon carbide yog ib hom tshwj xeeb ntawm silicon carbide uas yog tsim los ntawm cua sov thiab ua qee yam ntawm cov xuab zeb thiab cov ntaub ntawv carbon. Nws yog hu ua "ntsuab" vim nws muaj xim ntsuab thiab tsis huv dua li lwm hom silicon carbide. Ntsuab silicon carbide kuj paub txog nws cov thermal conductivity thiab tsawg thermal expansion.

Ntsuab silicon carbide yog siv nyob rau hauv ntau daim ntawv thov sib txawv. Ib qho ntawm feem ntau yog raws li cov khoom siv abrasive hauv kev sib tsoo lub log, cov cuab yeej txiav, thiab lwm yam khoom siv abrasive. Nws kuj tseem siv rau hauv cov ntaub ntawv refractory, ceramics, thiab lwm yam kev siv kub kub vim nws cov thermal conductivity thiab tsawg thermal expansion.

Lwm daim ntawv thov ntawmntsuab silicon carbideyog nyob rau hauv zus tau tej cov semiconductor wafers. Silicon carbide yog siv los ua cov khoom siv substrate rau kev tsim cov khoom siv hluav taws xob siab, lub zog hluav taws xob. Qhov no yog vim nws muaj qhov dav bandgap, txhais tau tias nws tuaj yeem ua hluav taws xob ntawm qhov kub thiab txias thiab tsis muaj zog dua li lwm cov ntaub ntawv.

Ntsuab silicon carbide kuj tseem siv rau hauv kev tsim cov hnub ci hlwb. Cov khoom siv yog siv los ua substrate rau kev loj hlob ntawm gallium nitride (GaN) txheej, uas yog siv los tsim cov hnub ci hluav taws xob ua haujlwm siab. Kev siv ntsuab silicon carbide ua cov khoom siv substrate tuaj yeem ua rau muaj txiaj ntsig ntau dua thiab muaj txiaj ntsig zoo hnub ci cell ntau lawm.

Ntxiv rau nws cov ntawv thov kev lag luam ntau dua, ntsuab silicon carbide kuj tseem siv rau hauv kev kos duab thiab cov hniav nyiaj hniav kub. Cov khoom siv yog siv los tsim carvings, sculptures, thiab lwm yam khoom zoo nkauj. Nws cov hardness siab thiab cov xim tshwj xeeb ua rau nws cov khoom zoo nkauj rau cov neeg ua yeeb yam thiab cov neeg tsim qauv.

Hauv kev xaus,ntsuab silicon carbideyog ib hom tshwj xeeb ntawm silicon carbide uas yog siv rau ntau yam kev siv sib txawv. Los ntawm cov khoom siv abrasive mus rau cov khoom siv hluav taws xob kub kub thiab txawm tias kos duab thiab cov hniav nyiaj hniav kub, ntsuab silicon carbide yog cov khoom muaj txiaj ntsig nrog cov khoom tshwj xeeb uas ua rau nws tseem ceeb hauv ntau qhov kev lag luam.
