Kev ua tau zoo ntawm cov khoom siv ceramic tshwj xeeb yog txiav txim siab los ntawm ob yam. Ua ntej, cov khoom siv, cov khoom siv tshuaj lom neeg tseem ceeb, cov qauv siv lead ua. Lawv txiav txim siab cov khoom ntawm cov ntaub ntawv ceramic, xws li kub tsis kam, semiconductivity thiab rwb thaiv tsev. Thib ob, lub microstructure, suav nrog kev faib tawm, qhov loj me, cov duab, qhov pore loj faib, impurities, tsis xws luag, thiab lwm yam. Ordinary ceramics yog ua los ntawm av nplaum, feldspar, thiab quartz ua raw cov ntaub ntawv, uas yog npaj thiab sintered. Cov ceramics no yog ib qho nyuaj hauv kev ntxhib los mos, tsis oxidize thiab xeb, yog corrosion-resistant, tsis muaj hluav taws xob, tuaj yeem tiv taus qhov kub thiab txias, muaj kev ua haujlwm zoo thiab tus nqi qis, tab sis muaj zog tsawg. Kev siv dav dav kub tsis tshaj 1200 degrees Celsius. Hom ceramic no muaj cov zis loj thiab ntau hom, thiab yog siv dav hauv hluav taws xob, tshuaj thiab lwm yam lag luam.

Silicon carbide hmoov siv rau silicon carbide ceramics yog tsim los ntawm cov hmoov metallurgy los ntawm cov tshuaj tiv thaiv sintering lossis kub nias sintering txheej txheem. Silicon carbide ceramics yog tus cwj pwm los ntawm qhov kub thiab txias zog, zoo thermal stability, thiab zoo hnav tsis kam thiab creep kuj. Haum rau casting hlau caj pas nozzles, lub tes tsho thermocouple, roj turbine hniav, bearings thiab lwm yam. Nyob rau tib lub sijhawm, vim tias nws cov thermal conductivity siab, nws kuj tseem tsim nyog rau cov khoom siv hluav taws xob sib hloov hauv qhov kub thiab txias, thiab tseem tuaj yeem siv los ua ntau yam twj tso kua mis.
Silicon nitride ceramics yog nplua nuj nyob rau hauv raw cov ntaub ntawv thiab zoo nyob rau hauv processability, thiab muaj peev xwm tsim ntau yam me me qhov tseeb ntawm tus nqi qis, tshwj xeeb tshaj yog qhov chaw nrog cov duab complex, thiab cov tawm los yog siab dua lwm yam ntaub ntawv ceramic. Silicon nitride ceramics muaj kev tiv thaiv zoo rau kev hloov pauv kub ceev thiab siab hardness. Nws hardness yog thib ob tsuas yog cov khoom xws li pob zeb diamond thiab boron nitride. Lub cav yog ua los ntawm cov khoom siv silicon nitride ceramic. Raws li kev khiav hauj lwm kub nce mus rau 1370 degrees Celsius, lub cav efficiency yuav nce 30%. Nyob rau tib lub sijhawm, vim qhov kub thiab txias, cov roj tuaj yeem hlawv tag nrho, thiab cov pa phem ntawm cov pa hluav taws xob yuav raug txo kom tsawg, uas tsis yog tsuas yog txo lub zog noj, tab sis kuj txo cov pa phem ib puag ncig.

Muaj ntau lwm yam khoom siv tshwj xeeb ceramic. Lawv muaj lawv tus kheej cov yam ntxwv thiab tuaj yeem ua rau ntau yam kev ua haujlwm. Lithium oxide ceramics yog cov ntaub ntawv kub kub, talc ceramics yog cov khoom siv hluav taws xob ntau zaus, thorium oxide ceramics yog cov khoom siv hluav taws xob, barium titanate ceramics yog cov khoom siv hluav taws xob, thiab cov cermets xws li borides, nitrides, thiab silicides yog cov ntaub ntawv kub kub. Ferrite ceramics yog siv rau cov hlau nplaum, nco cov hlau nplaum, lub taub hau sib nqus thiab lwm yam ntaub ntawv, lub ntiaj teb tsis tshua muaj cobalt porcelain yog siv rau cov ntaub ntawv nco, thiab semiconductor ceramics yog siv rau cov ntsiab lus tseem ceeb, hnub ci hlwb thiab lwm yam ntaub ntawv.
