Khoom Description
Silicon nitride (Si3N4) yog ib qho khoom siv tsis muaj zog uas muaj silicon thiab nitrogen, nrog rau cov tshuaj formula Si3N4. Nws yog ib qho tseem ceeb ntawm cov khoom siv ceramic. Nws muaj ob lub ntsiab siv lead ua: -Si3N4 thiab -Si3N4. Lub qub yog granular siv lead ua thiab tom kawg yog koob-puab siv lead ua. Ob leeg muaj nyob rau hauv hexagonal system.
Silicon nitride muaj siab hardness, thib ob tsuas yog pob zeb diamond thiab cubic boron nitride, thiab muaj zog khoov siab heev. Silicon nitride nws tus kheej muaj lubricity, tsis tshua muaj kev sib txhuam coefficient thiab hnav tsis kam. Silicon nitride muaj thermal stability zoo thiab muaj zog oxidation tsis kam. Lub thermal oxidation tsis kam kub tuaj yeem ncav cuag 1400 degree, kev ua haujlwm kub tuaj yeem ncav cuag 1200 degree, thiab kev ua haujlwm kub tuaj yeem ncav cuag 1800 degree hauv qhov nruab nrab lossis txo qhov cua. Tsis tas li ntawd, silicon nitride muaj tsawg thermal expansion thiab tuaj yeem siv rau hauv qhov chaw ua haujlwm txias thiab kub kub. Silicon nitride muaj kev ruaj ntseg zoo, tuaj yeem tiv taus cov kua qaub feem ntau, thiab tsis ntub los yog corroded los ntawm ntau cov hlau molten lossis alloys xws li txhuas, txhuas, tin, nyiaj, tooj dag, thiab npib tsib xee.
Silicon nitride ua ke nrog cov khoom siv silicon carbide refractory yog dav siv nyob rau hauv lub duav ntawm lub qhov cub, lub rauv plab, lub cev lub cev thiab lwm yam. Nyob rau hauv cov txheej txheem steelmaking, silicon nitride refractory cov ntaub ntawv yog siv nyob rau hauv lub swb phaj cov khoom nyob rau hauv qab ntawm lub ladle, uas txhim kho cov hnav tsis kam, yaig kuj thiab kev pab cuam lub neej ntawm cov swb phaj. Hauv cov cuab yeej thauj mus los xws li tsheb torpedo, cov khoom siv silicon nitride refractory yog siv rau hauv ob sab phlu, uas txhim kho nws cov corrosion kuj, hnav tsis kam thiab yaig kuj. Nyob rau hauv cov txheej txheem smelting ntawm non-ferrous hlau xws li txhuas, tooj liab, thiab zinc, silicon nitride ceramics yog siv los tsim cov khoom kub kub xws li ntsuas kub ntsuas thermocouple tes tsho, smelting furnace linings, ntim hauv ob sab phlu, crucibles, thiab lwm yam. wetting cuab yeej ntawm silicon nitride nrog hlau daws ua rau nws ua tau zoo nyob rau hauv cov cheeb tsam no.
Nyob rau hauv cov khoom siv huv si, ceramics txhua hnub, hluav taws xob ceramics, architectural ceramics thiab lwm yam kev lag luam, silicon nitride ua ke nrog silicon carbide refractory cov ntaub ntawv raws li cov khoom siv hauv cov rooj tog zaum txhim kho firing efficiency thiab cov khoom zoo. Kiln rooj tog cov ntaub ntawv xws li silicon nitride rollers ua tau zoo ntawm qhov kub thiab txias, ncua kev pab cuam lub neej thiab txo kev siv zog. Qhov chaw ua hauj lwm ntawm cov khib nyiab incinerators yog complex, yuav tsum tau cov ntaub ntawv refractory kom muaj kub zoo zog, hnav tsis kam, acid thiab alkali corrosion kuj, thermal shock stability, thiab lwm yam. Silicon nitride ua ke nrog silicon carbide cov ntaub ntawv tau lug siv nyob rau hauv khib nyiab incinerators thiab muaj. ua tau zoo.
