Silicon nitride feem ntau yog siv hauv kev tsim cov ceramics thiab cov alloys siab heev.
Hauv kev lag luam hluav taws xob, silicon nitride lub siab insulating zog thiab qis thermal expansion coefficient ua rau nws cov khoom ntim zoo tagnrho. Tsis tas li ntawd, silicon nitride kuj tau siv dav hauv kev tsim hluav taws xob kub kub, aerospace, khoom siv kho mob thiab lwm yam.
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov teb ntawm silicon nitride yuav nthuav dav ntxiv. Kev npaj ntawm silicon nitride feem ntau yog ua los ntawm cov kauj ruam hauv qab no: silicon hmoov thiab nitrogen yog reacted nyob rau hauv qhov kub thiab txias tej yam kev mob los tsim silicon nitride; Tom qab ntawd, cov khoom tau txais los ntawm cov txheej txheem xws li crushing, ntxuav, thiab ziab. Cov kws tshawb fawb Suav tau siv txoj hauv kev no los ua tiav kev npaj siab-purity silicon nitride hmoov. Silicon nitride muaj cov yam ntxwv ntawm siab hardness, siab melting point, corrosion kuj, thiab lwm yam. Nws lub zog thiab hardness yog piv rau pob zeb diamond.
Tsis tas li ntawd, silicon nitride yog thermally thiab chemically ruaj khov, tso cai rau nws kom ruaj khov kev ua tau zoo nyob rau hauv high kub thiab corrosive ib puag ncig. Cov yam ntxwv no ua rau silicon nitride muaj dav daim ntawv thov kev cia siab nyob rau hauv high-temperature engine manufacturing, aerospace, khoom kho mob thiab lwm yam teb.
Txhawm rau ua kom tiav, silicon nitride, raws li cov khoom siv tsis muaj hlau tsis zoo, muaj cov khoom tshwj xeeb thiab kev siv dav. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, nws cov ntawv thov kev cia siab yuav nthuav dav. Peb yuav tsum ua qhov kev tshawb fawb tob tob thiab kev tsim cov khoom siv silicon nitride los txhim kho nws cov kev ua tau zoo thiab kev siv cov peev txheej thiab pab txhawb kev txhim kho ntawm peb lub teb chaws.
