Zircon corundum block imapangidwa ndi mchenga wokhazikika wa zircon komanso zopitilira 64% zircon. zircon corundum fire block imatsanuliridwa mu nkhungu itasungunuka mu ng'anjo yamagetsi yamagetsi. mawonekedwe a lithofacies amakhala ndi eutectoid ndi magalasi magawo a corundum ndi zirconium plagioclase. zircon corundum refractory block petrographic structure imapangidwa ndi eutectoid ndi galasi gawo la corundum ndi zirconium clinopyroxene. midadada ya zircon corundum imakhala ndi mphamvu zamakina apamwamba, kukana kwamphamvu kwamafuta, kukana kwambiri pansi pa katundu, kukana kukokoloka kwamphamvu komanso kachulukidwe kakang'ono.
Njerwa ya Zirconia corundum imakonda kuchuluka kwa 1: 1 mchenga wa zircon ndi ufa wa alumina wa mafakitale ndikuwonjezera ma volume ochepa a NaZO, B20 wothandizila wosakanikirana mukamasakaniza bwino posungunula ndikutsanulira mu nkhungu pa kutentha kwakukulu kwa 1900 ~ 2000 ℃ kuchititsa njerwa zosakanizidwa zomwe zili ndi 33. % ZrO2 zomwe zili. Patsinde, tengani gawo la mchenga wa zircon wa desilicication ngati zopangira kuti mupange njerwa zosakanikirana ndi 36% ~ 41% ZrO2.
AZS-33
AZS33 zirconia corundum njerwa wandiweyani microstructure imapangitsa galasi kugonjetsedwa ndi kukokoloka kwa magalasi sikophweka kutulutsa miyala kapena zolakwika zina, ndipo kuthekera kopanga thovu laling'ono la gasi ndilotsika kwambiri.
AZS-36
Kuphatikiza pa eutectic yofanana ndi AZS-33 zirconia corundum firebrick, njerwa ya AZS-36 ya zirconia corundum chifukwa chowonjezera makristasi ochulukirapo ngati zirconia, ndipo magalasi amachepa.
AZS-41
Njerwa yamoto ya AZS-41 ya zirconia corundum imakhala ndi kugawa kofanana kwa makhiristo a zirconia, mu zirconia corundum mndandanda, kukana kukokoloka kwake ndikobwino kwambiri.

Zircon corundum midadada imagwiritsidwa ntchito makamaka mu ng'anjo yamagalasi yamafakitale, ng'anjo yamagetsi yamagalasi, ng'anjo yachitsulo yachitsulo ndi zitsulo, ng'anjo yamafakitale ya sodium metasilicate pokana kukokoloka kwamankhwala ndi makina pakutentha kwambiri.
