Hauv cov qhov cub kub siab ntawm kev tsim khoom lag luam thiab cov xwm txheej tseeb ntawm kev tsim khoom semiconductor, muaj ib qho khoom tseem ceeb zoo li qub tab sis tsis tuaj yeem tsis tau - silicon carbide square beam. Nws tsis yog qhov muag pom zoo li cov khoom kawg, tab sis nrog nws cov kev ua tau zoo tshwj xeeb, nws tau dhau los ua "tus saib xyuas tsis pom" ntawm ntau qhov chaw tsim khoom siab. Niaj hnub no, hauv lus yooj yim, peb yuav qhia koj txog cov khoom siv tshiab no uas muaj cov txuj ci tshwj xeeb.
Qhov zoo ntawm lub hauv paus ntawmsilicon carbide square beamslos ntawm qhov tshwj xeeb ntawm nws cov khoom siv raw silicon carbide. Cov khoom siv no, uas yog tsim los ntawm silicon thiab carbon, muaj tsawg heev hauv xwm thiab feem ntau yog artificially synthesized hauv kev lag luam. Nws qhov nyuaj yog qhov thib ob tsuas yog pob zeb diamond thiab muaj zog dua li cov khoom siv hlau ib txwm muaj. Tom qab ua tiav rau hauv cov qauv beam square, nws ua kom nws cov txiaj ntsig zoo tshaj plaws thiab dhau los ua "tus txiv neej tawv" uas muaj peev xwm tiv taus qhov chaw ib puag ncig hnyav.
Qhov tshwj xeeb ntawm silicon carbide square beams yog qhov ua tau zoo heev rau kev tiv taus kub. Hauv cov qhov cub hluav taws xob uas muaj ntau txhiab degrees Celsius, cov hlau ib txwm twb mos thiab deformed lawm, thaum silicon carbide square beams tuaj yeem tswj tau lawv cov duab kom ruaj khov thiab yuav tsis deform vim kub siab. Qhov "kev tiv taus kub siab" no ua rau nws yog qhov kev xaiv zoo tshaj plaws hauv cov xwm txheej uas xav tau kev ua haujlwm kub siab, tsis tas yuav hloov pauv ntau zaus, txo qhov poob ntau lawm.
Ntxiv rau qhov kub thiab txias tsis kam, nws "kev tsim khoom tsis kam" kuj pom tseeb hauv kev tiv thaiv corrosion thiab lub zog siab. Hauv cov chaw ua haujlwm, nws yog qhov tsis zam kom ntsib cov tshuaj corrosive xws li acid thiab alkali. Qhov saum npoo ntawm silicon carbide square beams tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ruaj khov kom tiv taus ntau yam tshuaj lom neeg tawm tsam thiab yuav tsis xeb lossis puas tsuaj. Tib lub sijhawm, nws yog lub teeb tab sis muaj peev xwm thauj khoom muaj zog. Raws li cov qauv thauj khoom ntawm cov khoom siv, nws tuaj yeem ua kom muaj kev txhawb nqa ruaj khov yam tsis ntxiv ntau lub nra rau tag nrho cov khoom siv, thiab tseem tuaj yeem txo kev siv hluav taws xob.
Txij li cov khoom siv txhawb nqa rau kev hlawv ceramic, mus rau cov khoom siv tseem ceeb rau kev tsim khoom semiconductor, thiab rau cov khoom tiv taus kub siab hauv thaj chaw ntawm lub zog tshiab, silicon carbide square beams muaj nyob rau hauv ntau yam lag luam tseem ceeb. Nws tsis muaj cov qauv nyuaj, tab sis daws cov teeb meem uas cov ntaub ntawv ib txwm tsis tuaj yeem daws tau nrog kev ua tau zoo, ua lub hauv paus tseem ceeb ntawm txoj kev mus rau kev txhim kho kev tsim khoom siab.
Nrog rau kev nce qib ntawm cov thev naus laus zis tshiab, cov xwm txheej siv ntawm silicon carbide square beams tseem nthuav dav. Qhov "kev txhawb nqa hardcore" zais no tau pab txhawb kev txhim kho zoo ntawm ntau yam lag luam nrog nws cov kev ruaj khov, kev ruaj khov, thiab kev ntseeg tau, ua lub zog thev naus laus zis tsis pom tab sis tseem ceeb.
