Silicon nitride tseem muaj ntau yam kev siv hauv lub neej. Cov tshuaj formula ntawm silicon nitride yog Si3N4. Nws cov khoom siv raw yog silicon hmoov. Cov hmoov silicon yog thawj zaug ua rau hauv cov duab koj xav tau, thiab tom qab ntawd hauv nitrogen ntawm qhov kub ntawm 1200 degrees Celsius. Cov hmoov silicon yog nitrided, thiab nws twb muaj ib co degree ntawm toughness. Tom qab ntawd cov hmoov silicon yog nitrided rau zaum ob ntawm qhov kub thiab txias. Lub zog ntawm silicon nitride tau txais yog siab heev, ntawm 1900 degrees Celsius. Nws yuav decompose nyob rau hauv siab kub, tsis muaj melting point, zoo thermal conductivity thiab me me thermal expansion coefficient.
Nws tuaj yeem siv los ua lub teeb ci ntsa iab vim nws cov hluav taws xob rwb thaiv tsev thiab ceev cua txias thiab cua sov. Silicon nitride kuj hnav-resistant, corrosion-resistant, thiab tsis yooj yim oxidized, yog li nws tau siv los ua hlau txiav cov cuab yeej.
Siv cov rwb thaiv tsev thiab corrosion tsis kam ntawm silicon nitride, nws tseem tuaj yeem siv los ua cov ntaub thaiv hluav taws xob thiab cov nplhaib sib nqus, feem ntau yog siv los tiv thaiv cov hluav taws xob hluav taws xob. Hom kev tiv thaiv no yuav siv sij hawm ntev thiab yuav tsis tau txais hluav taws xob poob thaum siv. cuam tshuam, rau qee qhov txo cov kev puas tsuaj los ntawm ntuj yam.
Silicon nitride muaj qhov sib txhuam me me thiab nws tus kheej lubricity, yog li nws kuj tseem siv rau hauv kev ua haujlwm ntawm kev siv tshuab. Nws hardness yog siab, thib ob tsuas yog pob zeb diamond, yog li nws kuj yog siv rau hauv kev sib tsoo ultra-zoo.
Vim tias silicon nitride tuaj yeem tiv taus qhov cuam tshuam ntawm kev hloov pauv kub thiab txias, nws yog lub teeb hauv qhov hnyav thiab muaj zog, yog li tib neeg kuj siv qhov zoo ntawm qhov no los ua cov kabmob dov. Vim tias hom kabmob no nyuaj dua li cov hlau, nws txo qhov kev sib txhuam nrog cov kabmob khiav. Kev sib cuag, feem ntau cov kabmob no tuaj yeem pom ntawm cov tsheb kauj vab thiab skates.
