Izitena zodongwe kwiziko leglasi

Izinto eziphambili zezitena zodongwe ziyi-Al2O3 kunye ne-SiO2, umxholo we-Al2O3 ngu-30% -45%, i-SiO2 yi-51% -66%, ubuninzi be-1.7-2.4g / cm3, i-porosity ebonakalayo yi-12% -21%, kunye nokusebenza okuphezulu. iqondo lobushushu Yi 1350℃ 1500℃. Kwishishini leglasi, i-bottom ye-kiln yakhiwe ngezitena zodongwe. Iindonga zedama ezisebenzayo kunye neepaseji, iindonga zokuhlaziya kunye nee-arches, izitena ezisezantsi zokujonga kunye nomkhuhlane. Njengoko iqondo lokushisa linyuka, umthamo wezitena zodongwe uya kwanda. Xa izinga lokushisa lidlula i-1450 ° C, umthamo uya kuncipha kwakhona.
