Al2O 3 iyo MgO waxaa lagu daraa iyadoo loo eegayo nidaamka ternary SiO 2-cao-na2o, taas oo ka duwan muraayadda saxanka ah in waxa ku jira Al2O 3 uu sarreeyo oo ka kooban CaO uu sarreeyo, halka maadada MgO ay tahay mid hoose.
Si kastaba ha noqotee nooca qalabka wax lagu dhejiyo, haddii ay tahay dhalooyinka biirka, dhalooyinka khamriga, gasacadaha waxaa loo isticmaali karaa maaddooyinka noocan oo kale ah, kaliya waxay u baahan yihiin in la sameeyo waxoogaa hagaajin ah iyadoo loo eegayo xaaladda dhabta ah. Kala duwanaanshaheeda (jajabka tirada badan) waa: SiO 27% ~ 73%, A12O 32% ~ 5%, CaO 7.5% ~ 9.5%, MgO 1.5% ~ 3%, R2O 13.5% ~ 14.5%.
Walaxda noocaan ah waxaa lagu gartaa aluminium dhexdhexaad ah, isticmaalka Al2O3 oo ka kooban ciid silica ah, ama soo bandhigida biraha alkali ee feldspar si loo badbaadiyo kharashka. Qadarka CaO + MgO waa mid aad u sarreeya, xawaaraha adkaantuna waa mid aad u degdeg badan, si loola qabsado xawaaraha mashiinka sare, qayb ka mid ah MgO ayaa loo isticmaalaa halkii CaO si looga ilaaliyo muraayadda inay ku dhalato daloolka socodka dareeraha, quudinta. marinka iyo mashiinka quudinta. Dhexdhexaad Al2O3 waxay wanaajin kartaa xoogga farsamada iyo xasiloonida kiimikada muraayadda.
