Al2O 3 ndi MgO amawonjezedwa pamaziko a SiO 2-cao-na2o ternary system, yomwe ili yosiyana ndi galasi la mbale kuti zomwe zili mu Al2O 3 ndi zapamwamba komanso zomwe zili mu CaO ndi zapamwamba, pamene zomwe zili mu MgO ndizochepa.
Ziribe kanthu kuti ndi mtundu wanji wa zida zopangira, kaya ndi mabotolo amowa, mabotolo a mowa, zitini zingagwiritsidwe ntchito zosakaniza zamtunduwu, zimangofunika kukonza bwino malinga ndi momwe zilili.Kapangidwe kake (kachigawo kakang'ono) ndi: SiO 27% ~ 73%, A12O 32% ~ 5%, CaO 7.5% ~ 9.5%, MgO 1.5% ~ 3%, R2O 13.5% ~ 14.5%.
Zosakaniza zamtunduwu zimadziwika ndi zitsulo zotayidwa zochepetsetsa, kugwiritsa ntchito Al2O3 yomwe ili ndi mchenga wa silika, kapena kuyambitsa ma alkali oxides ndi feldspar kuti apulumutse ndalama.Kuchuluka kwa CaO + MgO ndikokwera kwambiri, ndipo liwiro lowumitsa ndilothamanga kwambiri, kuti agwirizane ndi liwiro la makina apamwamba, gawo la MgO limagwiritsidwa ntchito m'malo mwa CaO kuteteza galasi kuti lisapangike mu dzenje lamadzimadzi, kudyetsa. njira ndi kudyetsa makina.Zolimbitsa Al2O3 zimatha kusintha mphamvu zamakina ndi kukhazikika kwagalasi.
