Kev tiv taus kub siab yog ib qho tseem ceeb ntawm cov xim hlau oxide hauv cov ntawv thov ceramic. Thaum hlawv hauv qhov cub ntawm qhov kub ntawm 1000 ° C txog 1300 ° C, cov xim no khaws lawv cov xim kom zoo, tsis zoo li ntau cov xim organic uas lwj lossis ploj mus rau hauv qhov kub heev. Qhov kev ruaj khov no ua kom ntseeg tau tias cov iav ceramic thiab cov vuas khaws lawv cov xim xav tau tom qab hlawv, qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo sib xws hauv kev tsim khoom loj thiab cov khoom siv tes ua kos duab. Txawm hais tias siv rau hauv cov iav ci lossis matte, cov xim hlau oxide xa cov xim txhim khu kev qha, tso cai rau cov chaw tsim khoom tsim cov vuas thiab cov khoom siv tes ua nrog cov xim sib xws.

Kev txhim kho xim ruaj khov yog lwm qhov zoo ntawm cov xim hlau oxide hauv cov khoom siv ceramics. Lawv sib cuam tshuam nrog cov khoom sib txawv ntawm cov xim glaze, suav nrog cov uas muaj silica, alumina, thiab cov neeg sawv cev fluxing, ua rau muaj cov xim sib xws. Qhov kev kwv yees no yog qhov tseem ceeb rau kev kho kom zoo nkauj ntawm cov vuas, qhov twg cov vuas loj yuav tsum phim zoo meej los tsim cov qauv sib xws. Cov kws ua vaj tse kuj tseem ceeb rau qhov kev ruaj khov no, vim nws tso cai rau lawv sim nrog cov qauv glaze thaum tswj hwm cov xim kawg ntawm lawv cov khoom. Txij li cov xim liab tob thiab cov xim av nplua nuj mus rau cov xim daj sov thiab cov xim dub av, cov xim hlau oxide muab ntau yam xim ruaj khov uas txhim kho qhov zoo nkauj ntawm cov khoom siv ceramic.

Cov xim hlau oxide muaj ntau yam siv rau hauv cov khoom siv ceramic, tsim nyog rau ob qho tib si glaze thiab lub cev xim. Hauv glazes, lawv tuaj yeem tsim ntau yam teebmeem, los ntawm cov xim khov kho mus rau cov xim sib txawv lossis cov xim speckled, nyob ntawm qhov concentration ntawm cov xim thiab cov qauv glaze. Thaum ntxiv rau lub cev ceramic nws tus kheej, lawv tsim cov xim sib xws thoob plaws hauv cov khoom siv, tshem tawm qhov xav tau rau glazes hauv qee cov qauv kho kom zoo nkauj. Qhov kev hloov pauv no tso cai rau cov kws ua yeeb yam ceramic thiab cov chaw tsim khoom los tshawb nrhiav ntau yam kev tsim qauv, los ntawm cov qauv ib txwm mus rau niaj hnub.

Qhov sib xws ntawm cov xim hlau oxide nrog cov huab cua sib txawv yog lwm qhov txiaj ntsig. Lawv ua tau zoo hauv ob qho tib si oxidizing thiab txo qhov chaw, muab kev ywj pheej rau cov kws ua ceramics hauv lawv cov txheej txheem firing. Qhov kev hloov pauv no yog qhov tshwj xeeb tshaj yog rau kev tsim cov xim tshwj xeeb, vim tias tib cov xim tuaj yeem ua rau cov xim sib txawv me ntsis nyob ntawm qhov chaw ntawm lub kiln. Piv txwv li, liab hlau oxide yuav tshwm sim ntau dua hauv hluav taws oxidizing, thaum noj lub suab tob dua, nplua nuj dua hauv qhov chaw txo qis.

Kev siv nyiaj tsim nyog kuj ua rau muaj kev nyiam ntawm cov xim hlau oxide hauv cov khoom siv av nplaum. Lawv lub zog tinting siab txhais tau tias cov khoom me me mus tau ntev, txo cov nqi khoom siv. Tsis tas li ntawd, lawv qhov ruaj khov thiab kev ruaj khov txo cov khib nyiab, vim tias muaj tsawg daim raug tsis lees txais vim muaj xim tsis sib xws. Qhov no ua rau lawv yog qhov kev xaiv pheej yig rau ob qho tib si kev tsim cov vuas loj thiab cov chaw ua khoom siv av nplaum me me.

Hauv kev xaus lus, cov xim hlau oxide yog qhov zoo tagnrho rau cov iav ceramic thiab kho kom zoo nkauj pobzeb vim lawv tiv taus kub siab, xim ruaj khov, ntau yam, thiab pheej yig. Lawv ua rau muaj cov khoom siv ceramic zoo nkauj, ruaj khov, thiab muaj kev nyab xeeb, los ntawm cov vuas ua haujlwm mus rau cov khoom siv av nplaum zoo nkauj, ua tau raws li qhov xav tau ntawm cov chaw tsim khoom thiab cov neeg siv khoom.
