Ma muli o ka ʻōnaehana ternary SiO 2-CAO -Na2O, hoʻohui ʻia nā mea aniani o ka ʻōmole sodium a me ka calcium me Al2O 3 a me MgO. ʻO ka ʻokoʻa, ʻoi aku ka kiʻekiʻe o ka maʻiʻo o Al2O 3 a me CaO i loko o ke aniani omole, ʻoiai he haʻahaʻa ka ʻike o MgO. Hiki ke hoʻohana ʻia nā ʻano mea hana, nā ʻōmole pia, nā ʻōmole waiʻona, nā kini i kēia ʻano meaʻai, e like me ke kūlana maoli e hana i kahi hoʻokani maikaʻi.
ʻO kona mau ʻāpana (ʻāpana hapa nui) mai SiO 27% a 73%, A12O 32% a 5%, CaO 7.5% a 9.5%, MgO 1.5% a 3%, a me R2O 13.5% a 14.5%. Hōʻike ʻia kēia ʻano o ka haku mele ʻana e ka maʻi alumini haʻahaʻa a hiki ke hoʻohana ʻia e mālama i nā kumukūʻai ma o ka hoʻohana ʻana i ke one silica i loaʻa iā Al2O3 a i ʻole ka hoʻohana ʻana i ka feldspar e hoʻolauna i nā oxide metala alkali. ʻO CaO+MgO ka leo kiʻekiʻe a me ka wikiwiki paʻakikī.
I mea e hoʻololi ai i ka wikiwiki o ka mīkini kiʻekiʻe, hoʻohana ʻia kahi hapa o MgO ma kahi o CaO no ka pale ʻana i ke aniani aniani mai ka crystallized i loko o ka lua kahe, ke ala hānai a me ka mea hānai. Hiki i ka Al2O3 maʻalahi ke hoʻomaikaʻi i ka ikaika mechanical a me ke kūpaʻa kemika o ke aniani.
