Silicon Nitride Khoom

Silicon Nitride Cov Khoom Muag yog ua los ntawm sintered silicon nitride ceramic, uas yog cov tshuaj sib txuas ntawm cov tshuaj silicon thiab nitrogen (Si3N4) los ntawm chav kawm ntawm nitrides. Silicon nitride sintered cov khoom lag luam yog tus cwj pwm los ntawm ntau yam khoom sib txawv uas ua rau daim ntawv thov muaj kev nthuav dav rau kev siv ntau yam. Vim nws lub zog loj thiab tsis tshua muaj thermal expansion coefficients, cov khoom ntawm silicon nitride Cheebtsam yog hom phiaj rau cov thermal hloov ntim. Sintered silicon nitride qhov chaw tseem tuaj yeem xa cov rog loj heev txawm tias qhov kub thiab txias nyob ib ncig ntawm 1,000 degrees Celsius thiab tuaj yeem siv zoo rau kev siv soldering thiab vuam.

Si3N4 Silicon Nitride cov khoom muaj cov yam ntxwv zoo heev thiab lub cev tawv. Sij hawm dhau los, nws tau siv nyob rau hauv qhov chaw ib puag ncig hnyav, xws li tub rog, semiconductor, precision tshuab, thiab lwm yam, thiab qhov kev thov tau ruaj khov. Txawm li cas los xij, muaj kev hloov pauv hauv kev ua lag luam tsis ntev los no: piv txwv li, Si3N4 silicon nitride hmoov cov khoom siv hauv qhov ncauj qhov ntswg tuaj yeem thaiv txoj kev kis tus kabmob coronavirus; thiab nws lub nrawm them thiab paug cov yam ntxwv ruaj ntseg tau dhau los ua qhov kev tshawb fawb txog kev pom zoo rau cov roj teeb lithium anode; Nrog txoj kev loj hlob ntawm peb lub semiconductor thiab hluav taws xob tsheb kev lag luam, lub zog hluav taws xob muaj qhov xav tau ntau rau cov nplais hluavtaws ua tiav nrog cov thev naus laus zis thiab siab thermal conductivity, uas ua rau muaj kev nce siab hauv kev thov rau Si3N4 silicon nitride hmoov thiab substrates. Tib lub sijhawm, txhawm rau ua kom tau zoo dua qhov kev ruaj khov ntawm cov kev lag luam tsheb tshiab yav tom ntej, cov yam ntxwv ntawm cov ntaub ntawv yuav raug tsim los ntawm kev ntseeg siab thiab siab thermal conductivity. Piv txwv li, lub thermal conductivity tau txav los ntawm tam sim no 80 W / m · K mus rau lub hom phiaj ntawm 170 W / m · K. Tus yuam sij rau txoj kev loj hlob nyob rau hauv kev sib xyaw ntawm cov khoom siv tshiab, tsim cov txheej txheem, cov txheej txheem sintering, thiab microstructure tswj thiab lwm txoj kev tuaj yeem ua kom zoo ntxiv.
