Hauv ntau qhov xwm txheej ntawm kev tsim khoom lag luam, qhov chaw ib puag ncig hnyav xws li kub siab, xeb, thiab hnav feem ntau sim qhov ruaj khov ntawm ntau yam khoom siv.Silicon carbide ceramic tiv thaiv raj, ua ib yam khoom tseem ceeb uas tiv thaiv cov khoom tseem ceeb ntawm cov khoom siv, tab tom ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam nrog lawv cov txiaj ntsig tshwj xeeb. Nws tsis muaj cov qauv nyuaj, tab sis nrog "kev ua haujlwm tau zoo" ua nws cov yam ntxwv tseem ceeb, nws tau dhau los ua "tus saib xyuas" uas ntseeg tau hauv cov chaw ua haujlwm.
Qhov zoo ntawm cov raj tiv thaiv silicon carbide ceramic yog los ntawm lawv cov khoom siv tshwj xeeb. Ua ntej, nws muaj zog heev rau qhov kub thiab txias thiab tuaj yeem tswj tau qhov ruaj khov txawm tias nyob rau hauv qhov kub siab tshaj 1000 degrees Celsius, tsis muaj kev hloov pauv lossis kev puas tsuaj. Qhov no ua rau nws yooj yim los tswj cov xwm txheej ua haujlwm kub siab xws li metallurgy thiab chemical engineering, tsim kom muaj "kev tiv thaiv" rau cov khoom tseem ceeb xws li sensors thiab cov khoom cua sov sab hauv. Qhov thib ob, nws qhov kev tiv thaiv corrosion zoo heev, thiab nws nyuaj rau cov tshuaj lom neeg xws li cov kua qaub thiab alkalis muaj zog, nrog rau cov pa roj pov tseg thiab kua dej ua rau nws puas tsuaj loj. Lub peev xwm "tiv thaiv corrosion" no ua rau lub neej ua haujlwm ntawm cov raj tiv thaiv ntev dua thiab txo qhov zaus thiab tus nqi ntawm kev saib xyuas cov khoom siv. Tsis tas li ntawd, cov khoom siv silicon carbide ceramic nws tus kheej muaj qhov nyuaj siab thiab hnav tsis kam zoo. Hauv cov xwm txheej uas kev sib txhuam yooj yim tshwm sim xws li kev thauj khoom thiab kev sib xyaw tshuab, nws tuaj yeem tiv taus hnav, tswj nws cov qauv, thiab zam kev cuam tshuam rau cov txheej txheem tsim khoom vim yog hnav khoom.
Hais txog cov xwm txheej siv tau, ntau yam kev siv ntawm silicon carbide ceramic tiv thaiv cov raj yog dav heev. Hauv kev lag luam metallurgical, nws tuaj yeem tiv thaiv cov ntsuas kub kom ntsuas qhov kub thiab txias hauv cov cub tawg kub rau steelmaking thiab ironmaking; Hauv kev lag luam chemical engineering, nws tuaj yeem tiv taus kev yaig ntawm cov kua qaub thiab alkaline thiab muab kev tiv thaiv rau kev saib xyuas cov khoom hauv cov hlab ntsha thiab cov kav dej; Hauv kev lag luam fais fab, nws tuaj yeem siv rau kev tiv thaiv cov khoom siv kub xws li boilers thiab turbines, kom ntseeg tau tias muaj kev tsim hluav taws xob tas mus li thiab ruaj khov; Tsis tas li ntawd, nws qhov muaj nyob kuj tuaj yeem pom hauv qhov kub thiab txias thiab corrosive ib puag ncig hauv kev lag luam xws li kev tiv thaiv ib puag ncig, cov ntaub ntawv tsim kho, thiab lub zog tshiab. Txawm hais tias nws yog kub hnyiab kub, tshuaj corrosion, lossis kev hnav khoom siv, tsuav yog nws yog ib puag ncig hnyav uas xav tau kev tiv thaiv, silicon carbide ceramic tiv thaiv cov raj tuaj yeem cia siab rau lawv tus kheej qhov zoo kom ntseeg tau tias kev ua haujlwm ib txwm ntawm cov khoom siv.
Raws li ib qho tseem ceeb tiv thaiv khoom hauv kev tsim khoom lag luam, silicon carbide ceramic tiv thaiv cov kav dej tau dhau los ua "cov neeg saib xyuas tawv" ntawm cov khoom siv hauv qhov chaw nyuaj vim lawv cov txiaj ntsig tseem ceeb ntawm kev tiv taus kub siab, tiv taus corrosion, hnav tsis kam, thiab zoo toughness. Nws muab kev lees paub rau kev tsim khoom ruaj khov hauv ntau yam lag luam nrog nws cov kev ua tau zoo yooj yim thiab tsis muaj kev dai kom zoo nkauj, thiab tseem tso cai rau ntau tus neeg nkag siab txog qhov tseem ceeb ntawm cov khoom siv silicon carbide ceramic. Nrog rau kev txhim kho tas mus li ntawm kev siv tshuab kev lag luam, cov xwm txheej ntawm kev siv silicon carbide ceramic tiv thaiv cov kav dej yuav txuas ntxiv nthuav dav, ua lawv lub luag haujlwm "tiv thaiv" hauv ntau qhov chaw thiab txhaj tshuaj lub zog ntev mus rau hauv kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm kev tsim khoom lag luam.
