Zircon corundum block an ƙera shi tare da barga zircon yashi da sama da 64% abun ciki na zircon. Zircon corundum block wuta ana zuba a cikin mold bayan an narke a cikin wutar lantarki narkewa. Tsarin lithofacies ya ƙunshi sassan eutectoid da gilashin corundum da zirconium plagioclase. Zircon corundum refractory block petrographic tsarin an yi shi da eutectoid da gilashin lokaci na corundum da zirconium clinopyroxene. Tubalan zircon corundum suna da fasalulluka na ƙarfin injina mai ƙarfi, juriya mai kyau na thermal shock, babban juriya a ƙarƙashin kaya, juriya mai ƙarfi da haɓaka mai yawa.
Tushen zirconia corundum ya fi son yashi na 1: 1 yashi zircon da foda alumina na masana'antu kuma yana ƙara ƙaramin ƙarar NaZO, wakilin B20 na fusion bayan haɗuwa daidai ta hanyar narkewa da zubowa cikin mold a babban zafin jiki na 1900 ~ 2000 ℃ wanda ya haifar da tubalin da aka haɗe da simintin ya ƙunshi 33. % ZrO2 abun ciki. A kan tushe, ɗauki wani ɓangare na yashi zircon desilicication azaman ɗanyen abu don yin tubalin da aka haɗa tare da abun ciki na 36% ~ 41% ZrO2.
