【摘要】 精确地测定了20Na₂O·xRO·（80-x）SiO₂玻璃粉末,当引入不同量的氧化物RO（MgO、CaO、SrO、BaO）后,在去离子水中Na₂O的浸出量,用“Apple”型微机将Na₂O浸出量与氧化物RO含量,R²⁺离子半径与R²⁺离子极化率之间的关系拟合出两个方程式。更多还原

【Abstract】 Different contents of oxides RO（MgO, CaO, SrO, BaO）were added to glasses in the system 20Na₂O·xRO·（80-x）SiO₂. and the amount of Na₂O leached from powdered samples prepared by these glasses in deionized water was measured.The measured results were best-fitted by an "Apple" type microcomputer to obtain the relationship between leached amount of Na₂O and RO contents in glasses and that between the radii and polarizabilities of R²⁺ thus two regression equations were presented.更多还原
