Silicon nitride (Si3N4) yog cov khoom siv ntau yam ceramic uas pom cov ntawv thov hauv ntau qhov kev lag luam vim nws cov khoom siv zoo heev, thermal, thiab tshuaj lom neeg. Qee qhov kev siv ntawm silicon nitride muaj xws li:
Advanced Ceramics thiab tej cuab yeej txiav
Silicon nitride yog siv dav hauv kev tsim cov khoom siv hluav taws xob zoo xws li cov cuab yeej txiav, cov kabmob, thiab cov ntsaws ruaj ruaj. Nws hardness, hnav tsis kam, thiab toughness ua rau nws tsim nyog rau kev thov kev lag luam.
Pob Bearings thiab Rollers
Silicon nitride yog siv rau hauv pob bearings thiab rollers rau ntau yam tshuab. Nws qis ntom ntom thiab kev nyuaj siab ua rau txhim kho kev ua tau zoo thiab ntev hauv kev sib piv rau tsoos hlau bearings.
Automotive Cheebtsam
Silicon nitride yog ua haujlwm nyob rau hauv daim ntawv thov tsheb, tshwj xeeb tshaj yog rau cov cav tov xws li turbochargers thiab bearings. Nws muaj peev xwm tiv taus qhov kub thiab txias thiab corrosive ib puag ncig ua rau nws muaj txiaj ntsig hauv kev lag luam tsheb.
Thaum tshav kub kub Exchangers
Vim nws zoo heev thermal conductivity thiab tsis kam mus rau thermal shock, silicon nitride yog siv nyob rau hauv manufacturing ntawm tshav kub exchangers. Qhov no yog ib qho tseem ceeb nyob rau hauv daim ntawv thov uas muaj peev xwm hloov hluav taws xob thiab kav ntev yog qhov tseem ceeb.
Electronics
Silicon nitride yog siv rau hauv kev tsim cov khoom siv hluav taws xob, xws li substrates rau kev sib xyaw ua ke. Nws cov khoom hluav taws xob rwb thaiv tsev thiab kev tiv thaiv thermal cycling ua rau nws haum rau cov ntawv thov no.
Biomedical Applications
Silicon nitride yog suav tias yog cov khoom siv biocompatible, thiab nws yog siv rau hauv kev kho mob cog xws li cov pob qij txha thiab cov hniav cog hniav. Nws cov khoom bioinert txo qhov kev pheej hmoo ntawm kev tsis zoo tshwm sim hauv tib neeg lub cev.
Aerospace Components
Silicon nitride yog siv rau hauv aerospace daim ntawv thov rau cov khoom uas xav tau lub zog siab, lub teeb yuag, thiab ua haujlwm rau huab cua. Piv txwv muaj xws li turbine hniav thiab lwm yam khoom siv hauv lub dav hlau tshuab.
Solar Cells
Silicon nitride yog siv los ua cov tshuaj tiv thaiv kev cuam tshuam hauv lub hnub ci hlwb. Nws cov khoom siv kho qhov muag pab txo qhov kev xav thiab ua kom lub zog ntawm lub hnub ci hloov pauv.
Thermocouple Protection Tubes
Silicon nitride raj yog siv los tiv thaiv sheaths rau thermocouples nyob rau hauv ib puag ncig kub. Lawv muab cov thermal poob siab zoo thiab tiv thaiv cov thermocouple los ntawm cov mob hnyav.
Kev lag luam semiconductor
Silicon nitride tuaj yeem siv los ua cov khoom siv hluav taws xob. Nws ua raws li daim npog qhov ncauj rau ion implantation, ib txheej passivation, thiab ib qho insulator hauv ntau cov khoom siv hluav taws xob.
