1.Qhov khoom plig
1） Crucible nrog alumina cov ntsiab lus ntau dua 95% yog hu ua corundum crucible.
（2） Corundum Ceramic crucibleis muaj li ntawm cov dej txau zoo faus alumina, uas yog qhov ua kom ruaj khov thiab refractory.
（3） Corundum Ceramic Crucible yog tsim nyog rau melting cov qauv nrog qee yam tsis muaj zog xws li anhydrous Na2C03 li flux, tab sis tsis haum rau melting cov qauv nrog cov muaj zog alkaline xws li Na 202 thiab NaOH thiab cov kua qaub (xws li K2S 207, thiab lwm yam) )
2. Qhov ntsuas
Alumina crucible thiab corundum crucible index Non-expansion ceramic crucible yog lub cim tiam tshiab ntawm cov khoom lag luam tom qab av nplaum, cordierite, quartz, thiab zaj duab xis-npog crucibles hauv Suav. Yixing Junteng refractory ceramics muaj cov khoom lag luam ntev ntev ntawm kev nthuav dav uas tsis txuas ntxiv rau daim ntaub qhwv. Corning' s cov khoom lag luam los ntawm Tebchaws Meskas yog qhov sib piv, thiab tau txais zoo los ntawm cov neeg siv rau lawv cov kev ua tau zoo tshaj plaws xws li lub neej siab thiab kev noj haus qis. Crucible 1. Ultra tsawg nthuav coefficient, siab thermal kev co stability ...
Peb, kev tu cev txheej txheem
1. Cov kua qaub ua kua: feem ntau tsau nrog nitric acid rau lub sijhawm ntev; tom qab ntawd ntxuav nrog dej
2. Ua kom qhuav, maj mam ua kom sov li 800 ℃ hauv qhov cub kub kub kom ntev li 6 teev
3. Coj nws tawm tom qab txias thiab siv nws.
4. Tshem tawm cov khoom tsis huv, hloov cov khoom tsis haum rau hauv soluble nitrate thiab tshem tawm.
5. Tshem tawm ntawm cov kab hluav taws xob nitrate nyob rau hauv crucible (txoj kev kho kom zoo thaum tshav kub kub): Nco ntsoov tias cov cua kub yuav tsum tsis ceev, txwv tsis pub lub crucible yuav ua rau tawv nqaij (puas pob)
