Cov khoom no pab txuas ntxiv lub neej ntawm cov khoom siv thaum txo cov nqi kho thiab hloov pauv hauv cov chaw ua haujlwm hnyav.
4. Hluav taws xob rwb thaiv tsev thiab lub teeb yuag tsim
Silicon nitride ua ke zoo heev hluav taws xob rwb thaiv tsev nrog tsawg ntom.
Piv nrog cov hlau thiab npib tsib xee-raws li alloys, nws qhov hnyav qis ua rau nws txaus nyiam rau cov ntawv thov uas xav tau lub teeb yuag, siab - lub zog, thaum nws cov hluav taws xob rwb thaiv tsev ua rau nws haum rau cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv semiconductor.
Cov ntawv thov ib txwm muaj xws li:
EV fais fab module substrate
Cov khoom siv semiconductor
High -ceev ceramic bearings
Aerospace structural Cheebtsam
Disadvantages ntawm Silicon Nitride Ceramic
Txawm hais tias silicon nitride muaj kev ua tau zoo, ntau qhov kev txwv yuav tsum tau txiav txim siab.
Tus nqi khoom siab dua
Silicon nitride yog kim kim tshaj li cov pa engineering ceramics xws li alumina.
High -purity hmoov, cov txheej txheem sintering zoo, thiab kev tswj xyuas nruj zoo tag nrho ua rau muaj nqi ntau dua, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob- qib.
Yooj yim rau tshuab
Nws tshwj xeeb hardness kuj ua rau silicon nitride nyuaj rau tshuab.
Ib txwm sib tsoo thiab drilling tuaj yeem ua rau:
Cov cuab yeej siv ceev ceev
Ntug chipping
Microcracks
