I-zircon corundum block ikhiqizwa ngesihlabathi se-zircon esizinzile kanye nokuqukethwe kwe-zircon engaphezu kuka-64%. I-zircon corundum fire block ithululelwa esikhunjeni ngemuva kokuncibilika esithandweni sokuncibilika sikagesi. isakhiwo se-lithofacies siqukethe izigaba ze-eutectoid nengilazi ze-corundum ne-zirconium plagioclase. I-zircon corundum refractory block petrographic structure yenziwe nge-eutectoid nengilazi isigaba se-corundum ne-zirconium clinopyroxene. I-zircon corundum blocks inezici zamandla aphezulu wemishini, ukumelana nokushaqeka okuhle kokushisa, ukuqina okuphezulu ngaphansi komthwalo, ukumelana nokuguguleka okuqinile kanye nokuminyana okuphezulu.
Isitini se-Zirconia corundum sithanda ukulinganisa kwesanti ye-zircon engu-1:1 kanye nempushana ye-alumina yezimboni bese wengeza ivolumu embalwa ye-NaZO, i-ejenti ye-B20 yokuhlanganisa ngemva kokuxutshwa kahle ngokuncibilika nokuthululelwa esikhunjeni ekushiseni okuphezulu kuka-1900 ~ 2000 ℃ okuholela ekutheni isitini esihlanganisiwe esiqukethe 33 % Okuqukethwe kwe-ZrO2. Esisekelweni, sebenzisa ingxenye yesihlabathi se-zircon yokwenza i-desilicication njengento eluhlaza ukuze wenze isitini esihlanganisiwe esinokuqukethwe okungu-36%~41% kwe-ZrO2.
I-AZS-33
I-AZS33 zirconia corundum isitini esiminyene se-microstructure yenza ingilazi imelane nokuguguleka kwengilazi ukusebenza kungabi lula ukukhiqiza amatshe noma okunye ukukhubazeka, futhi amathuba okukhiqiza amabhamuza amancane egesi aphansi kakhulu.
I-AZS-36
Ngaphezu kwe-eutectic efanayo ne-AZS-33 zirconia corundum firebrick, isitini se-AZS-36 zirconia corundum ngenxa yokwengezwa kwamakristalu e-zirconia afana neketango, nokuqukethwe kwengilazi kwehlile.
I-AZS-41
I-AZS-41 i-zirconia corundum isitini somlilo iqukethe ukusatshalaliswa okufanayo kwamakristalu e-zirconia, ochungechungeni lwe-zirconia corundum, ukumelana nokuguguleka kwayo kungcono kakhulu.

Amabhulokhi eZircon corundum asetshenziswa kakhulu esithandweni sezimboni sengilazi, isithando somlilo sikagesi sengilazi, imboni ye-slideway yensimbi nensimbi, isithando somlilo sezimboni se-sodium metasilicate sokumelana nokuguguleka kwamakhemikhali nokwemishini ekushiseni okuphezulu.
