Na_2O—CaO—Al_2O_3—SiO_2—H_2O系的研究具有重大的理論意义和实际意义,因其能确定溶液中氧化鋁的平衡濃度和相应的固相組成。利用这些資料能从理論上論证处理鋁硅酸盐的新的水化学法。文献中有关平衡鋁酸鈉溶液的組成随溫度的变化的資料,大多数是屬于对Na_2O—Al_2O_3—
The study of Na_2O-CaO-Al_2O_3-SiO_2-H_2O has great theoretical and practical significance because it can determine the equilibrium concentration of alumina and the corresponding solid phase composition in solution. The use of these data can theoretically demonstrate the new hydration process for the treatment of aluminosilicates. Literature on the equilibrium composition of sodium aluminate solution with temperature changes in the data, most of them belong to the Na_2O-Al_2O_3-
