An ƙara Al2O 3 da MgO bisa tsarin tsarin SiO 2-cao-na2o, wanda ya bambanta da gilashin farantin karfe a cikin abin da ke cikin Al2O 3 ya fi girma kuma abun ciki na CaO ya fi girma, yayin da abun ciki na MgO ya kasance ƙasa.
Ko da wane nau'in kayan gyare-gyare, ko kwalabe na giya, kwalabe na barasa, gwangwani za a iya amfani da irin wannan nau'in sinadaran, kawai buƙatar yin gyaran gyare-gyare bisa ga ainihin halin da ake ciki. Abubuwan da ke tattare da shi (masu yawan juzu'i) shine: SiO 27% ~ 73%, A12O 32% ~ 5%, CaO 7.5% ~ 9.5%, MgO 1.5% ~ 3%, R2O 13.5% ~ 14.5%.
Irin wannan nau'in sinadari yana da matsakaicin abun ciki na aluminum, amfani da Al2O3 mai dauke da yashi silica, ko gabatarwar alkali karfe oxides tare da feldspar don adana farashi. Adadin CaO + MgO yana da girma sosai, kuma saurin taurin yana da sauri, don dacewa da saurin injin mafi girma, ana amfani da wani ɓangare na MgO maimakon CaO don hana gilashin yin crystallizing a cikin ramin kwararar ruwa, ciyarwa. nassi da injin ciyarwa. Matsakaici Al2O3 na iya inganta ƙarfin injiniya da kwanciyar hankali na gilashi.
