Izitini zobumba zokokhela ingilazi

Izingxenye eziyinhloko zezitini zobumba ziyi-Al2O3 ne-SiO2, okuqukethwe kwe-Al2O3 kungu-30% -45%, i-SiO2 i-51% -66%, ukuminyana yi-1.7-2.4g / cm3, i-porosity ebonakalayo yi-12% -21%, futhi ukusebenza okuphezulu kakhulu izinga lokushisa ngu-1350 ~ 1500℃. Embonini yengilazi, phansi kweziko lakhiwe ngezitini zobumba. Izindonga zamachibi okusebenza kanye namaphaseji, izindonga zokuvuselela kabusha namakhothamo, izitini zokuhlola eziphansi kanye ne-flue. Njengoba izinga lokushisa likhuphuka, umthamo wezitini zobumba uzokhula. Uma izinga lokushisa lidlula i-1450 ° C, ivolumu izoncipha futhi.
