Nyob rau hauv cov txheej txheem firing ceramic, kev ua tau zoo ntawm cov khoom siv hluav taws xob yog ncaj qha ntsig txog cov khoom zoo thiab kev siv zog. Silicon carbide ru tsev panels thiab cordierite mullite slabs yog tam sim no ob hom kev siv ntau tshaj plaws ntawm cov rooj tog zaum hauv cov chaw ua haujlwm ceramic. Nrog rau lawv cov kev ua tau zoo tshaj plaws, lawv muab kev txhawb nqa txhim khu kev qha rau cov txheej txheem tua hluav taws sib txawv.
Silicon carbide shed panelsyog tsim los ntawm siab -purity silicon carbide ua raw khoom, uas yog recrystallized thiab sintered nyob rau hauv high kub. Lawv muaj qhov zoo heev - kub lub zog thiab oxidation tsis kam, thiab tuaj yeem siv tau ntev ntawm qhov kub siab tshaj 1350℃. Nws cov thermal conductivity siab tuaj yeem ua rau luv luv lub voj voog hluav taws xob thiab txo kev siv hluav taws xob; Nyob rau tib lub sijhawm, qhov saum npoo yog ntom thiab du, tsis muaj slag lossis deformation thaum siv, ua kom muaj kev huv ntawm cov khoom siv ceramic. Cov khoom no tsuas yog tsim nyog rau kev tua hluav taws kub ceev hauv qhov cub, cov menyuam kilns, thiab cov khoom siv hluav taws xob hauv kev lag luam xws li niaj hnub- siv cov ceramics, huv ceramics, hluav taws xob ceramics, thiab cov khoom sib nqus.
Covcordierite mullite pob zeb slabyog tsim los ntawm kev sib xyaw firing nrog mullite li cov pob txha thiab cordierite ua cov khoom siv hauv paus. Nws muaj qhov qis coefficient ntawm thermal expansion thiab zoo heev thermal shock kuj. Nws tsis yog ib qho yooj yim rau tawg nyob rau hauv qhov kub thiab txias ntau zaus thiab cua txias thiab cua sov ib puag ncig, thiab tuaj yeem siv nyab xeeb ntawm qhov kub siab tshaj 1250 degree. Cov khoom muaj qhov zoo thermal stability, muaj zog creep kuj, thiab kev pab lub neej ntev. Cov khoom no yog dav siv nyob rau hauv qhov qis - kub firing thiab glazing txheej txheem ntawm txhua txhua hnub- siv ceramics, architectural ceramics, thiab microcrystalline iav, tshwj xeeb tshaj yog tsim rau ntau lawm scenarios uas yuav tsum tau thermal shock stability.
