Raws li SiO 2-CAO -Na2O ternary system, sodium thiab calcium fwj iav cov khoom xyaw ntxiv nrog Al2O 3 thiab MgO.Qhov txawv yog tias cov ntsiab lus ntawm Al2O 3 thiab CaO hauv lub raj mis iav yog qhov siab, thaum cov ntsiab lus ntawm MgO kuj tsawg.Tsis muaj teeb meem dab tsi ntawm cov khoom siv molding, lub raj mis npias, lub raj mis cawv, cov kaus poom tuaj yeem siv cov khoom xyaw no, tsuas yog raws li qhov xwm txheej tiag tiag los ua qee qhov zoo.
Nws cov Cheebtsam (feem ntau) ranges ntawm SiO 27% mus rau 73%, A12O 32% mus rau 5%, CaO 7.5% mus rau 9.5%, MgO 1.5% mus rau 3%, thiab R2O 13.5% mus rau 14.5%.Hom kev muaj pes tsawg leeg no yog tus cwj pwm los ntawm cov ntsiab lus nruab nrab ntawm txhuas thiab tuaj yeem siv los txuag cov nqi los ntawm kev siv silica xuab zeb uas muaj Al2O3 lossis siv feldspar los qhia alkali hlau oxides.CaO + MgO muaj qhov ntim siab thiab nrawm nrawm nrawm.
Txhawm rau hloov mus rau lub tshuab nrawm dua, ib feem ntawm MgO yog siv los hloov CaO los tiv thaiv iav siv lead ua los ntawm crystallized nyob rau hauv lub qhov dej ntws, txoj kev pub thiab lub feeder.Nruab nrab Al2O3 tuaj yeem txhim kho lub zog txhua yam thiab tshuaj lom neeg ruaj khov ntawm iav.
