【摘要】 选择不同分相趋势的CaO-Al₂O₃-SiO₂系统玻璃,利用体视学参数描述了其分相形貌随热处理温度的变化。发现随热处理温度升高,富SiO₂分相液滴的等效直径D增大;单位体积内液滴数目N_v减少;液滴的形状因子基本不变（λ≈0.9）;但是体积分数V_v有最大值出现。更多还原

【Abstract】 The variation of the morphology of phase separation with heat-treatment temperature at a given time is described by stereology parameters. Glasses with different tendencies to phase separation are selected in the system CaO-Al₂O₃-SiO₂. It is shown that with in- creasing temperature, the equivalent circle diameter （D） of SiO₂-rich droplets increases; the number of the droplets per unit volume （N_v） decreases; the shape factor （λ） remains the same （≈0.9）; but the volume fraction （V_v） has a maximum.更多还原
