Khoom Description
Silicon nitride yog ib qho inorganic tshuaj nrog cov tshuaj formula Si3N4. Nws yog ib qho tseem ceeb ntawm cov khoom siv ceramic. Silicon nitride muaj qhov nyuaj heev, nrog rau Mohs hardness ntawm 9, thib ob tsuas yog ob peb cov ntaub ntawv superhard xws li pob zeb diamond. Nyob rau tib lub sijhawm, nws lub zog kuj tseem siab heev, nrog rau chav tsev kub dabtsi yog khoov lub zog txog li 980MPa, piv rau cov hlau alloy, thiab lub zog tuaj yeem tswj tau ntawm 1200 degree yam tsis muaj kev txo qis. Silicon nitride muaj thermal stability zoo heev, nrog lub melting point txog 1900 degree, thiab nyob ruaj khov thaum rhuab mus rau 1450 ~ 1550 degree hauv huab cua. Tsis tas li ntawd, nws kuj muaj qhov zoo thermal shock tsis kam thiab tuaj yeem tiv taus qhov kub thiab txias hloov pauv yam tsis muaj kev tawg. Cov yam ntxwv ntawm silicon nitride yog ruaj khov heev. Tsuas yog hydrofluoric acid, nws tsis hnov mob nrog lwm cov inorganic acids, tsis ntub ntau yam tsis-ferrous hlau melts (tshwj xeeb tshaj yog cov kua txhuas), thiab tuaj yeem tiv taus kev yaig ntawm ntau cov organic.
Muaj ntau txoj hauv kev los ua ke silicon nitride, suav nrog kev txo qis carbothermal, tshuaj vapor deposition, sol-gel txoj kev, thiab lwm yam.
Silicon nitride tuaj yeem siv los tsim cov cuab yeej txiav thiab hnav-tiv taus qhov chaw xws li cov kabmob, cov khoom siv, thiab cov ntsaws ruaj ruaj. Silicon nitride yog siv los tsim cov cav cav, turbine hniav, thiab lwm qhov chaw uas ua haujlwm nyob rau hauv qhov chaw kub. Silicon nitride cov ntaub ntawv yog siv nyob rau hauv lub cav qhov chaw xws li turbocharger rotors, bearings, thiab li qub los txhim kho cav efficiency thiab durability. Silicon nitride yog siv los ua corrosion-resistant thiab high-temperature resistant reactor qhov chaw, twj tso kua mis, thiab li qub, haum rau corrosive ib puag ncig xws li muaj zog acids thiab muaj zog alkalis. Silicon nitride tuaj yeem siv los ua thermal diffusion barrier, hluav taws xob rwb thaiv tsev txheej, thiab cov txheej txheem kev txhawb nqa khoom siv hauv semiconductor ua vim nws cov hluav taws xob zoo thiab thermal stability. Silicon nitride yog siv los ua cov khoom siv insulating hauv kev sib xyaw ua ke thiab cov khoom siv rau cov tshuab micromechanical. Silicon nitride yog siv los tsim cov khoom siv kho mob xws li cov pob qij txha thiab cov tawv nqaij tawv vim nws cov biocompatibility thiab hnav tsis kam. Silicon nitride tuaj yeem siv rau hauv cov txheej txheem kho qhov muag xws li cov tshuaj tiv thaiv kev cuam tshuam vim nws qhov pom kev pom zoo thiab kev tiv thaiv ib puag ncig. Silicon nitride yog siv los ua ib qho ntawm cov khoom siv hnub ci los txhim kho cov roj teeb, thiab tseem siv los ua ib qho tseem ceeb hauv cov roj hlwb. Silicon nitride yog siv los tsim cov khoom hnav-resistant thiab kub-resistant qhov chaw hauv precision ntsuas ntsuas, xws li precision bearings thiab sensor ntsiab.
