Silicon Nitride Hmoov SiN

Silicon nitride muaj zog heev, tshwj xeeb tshaj yog kub nias silicon nitride, uas yog ib qho nyuaj tshaj plaws nyob rau hauv lub ntiaj teb no. Nws yog qhov tiv taus kub heev, thiab nws lub zog tuaj yeem khaws cia kom txog thaum kub ntawm 1200 degree tsis poob, thiab nws yuav tsis yaj mus rau hauv cov yaj tom qab cua sov, thiab nws yuav tsis decompose mus txog 1900 degree, thiab nws muaj kev tiv thaiv zoo heev. corrosion kev ua tau zoo, muaj peev xwm tiv taus yuav luag txhua yamInorganic acids thiab tsawg dua 30% caustic soda tov, kuj tuaj yeem tiv thaiv corrosion ntawm ntau cov organic acids; Nyob rau tib lub sijhawm, nws yog cov khoom siv hluav taws xob ua haujlwm siab.

Silicon nitride - Cov khoom siv tshuaj formula Si3N4 dawb hmoov crystals; Melting point 1900 degree, ceev 3.44 g / cm3 (20 degree); Muaj ob hom: hom yog hexagonalDensely packed qauv; Hom yog cov qauv zoo li spar. Silicon nitride yog grey thaum muaj impurities lossis ntau silicon.

Silicon nitride ceramics muaj cov yam ntxwv ntawm lub zog siab thiab kub tsis kam, thiab muaj cov khoom siv zoo tshaj plaws ntawm cov khoom siv ceramic, xws li thermal shock resistance, oxidation resistance, hnav tsis kam thiab corrosion resistance, thiab yog thawj cov ntaub ntawv sib tw rau ceramics rau tshav kub. cav qhov chaw. Hauv kev lag luam tshuab, silicon nitride ceramics yog siv los ua cov kabmob, cov menyuam, lub rooj zaum lub nplhaib, cov cuab yeej siv, cov tshuab txiav tshiab, cov twj tso kua mis, cov khoom siv sib khi, thiab lwm yam.

Hauv kev lag luam tshuaj, silicon nitride ceramics yog siv los ua cov khoom hnav-resistant, corrosion-resistant Cheebtsam. Xws li pob li qub, lub cev twj tso kua mis, combustion vaporizers, lim, thiab lwm yam.

Hauv kev lag luam metallurgical, silicon nitride ceramics muaj tus kheej lubrication vim qhov kub tsis kam, kev sib txhuam me me. Nws ruaj khov rau feem ntau cov hlau thiab cov kev daws teeb meem alloy, yog li nws tuaj yeem siv los ua cov cuab yeej thiab tuag rau cov khoom siv hlau, xws li dial mandrels, extrusion, hlau dialing tuag, yob, conveyor rollers, cua sov khoom fixtures, thermocouple poob lawm, hlau kub. kev txhawb nqa kev kho mob, crucibles, thiab aluminiumLiquid conductionbattalion, aluminium clad hauv ob sab phlu, thiab lwm yam.
