摘　　要：通过将两种不同颜色的Na2O-CaO-SiO2系统乳浊玻璃在熔融状态时进行完全混合,获得类似天然石材条纹的乳浊玻璃。采用XRD、SEM等测试手段研究乳浊玻璃的分相过程,分析了R2O3(R=Al,B)含量变化对乳浊玻璃的显微结构及性能的影响。研究结果表明,该系统乳浊玻璃的乳浊机理是分相乳浊,着色剂对玻璃微观结构无显著影响;随着Al2O3含量增加,富磷相数量减少但其液滴尺寸增大。B2O3含量提高使富磷相尺寸减小,液滴尺寸和分布趋向均匀;Al2O3含量增加使玻璃的耐水性有所提高;而B2O3含量增加降低了玻璃的耐水性。In order to obtain a opaque glass with stripes similar to the natural stone by incompletely mixing two kinds of Na2O-CaO-SiO2 opaque glasses with different colors in the molten state.The phase-separation of opaque glass was studied by XRD,SEM and other methods,and effect of R2O3 （R=Al,B）content on microstructure and properties of the glass were analyzed.The results indicated that the opacifying mechanism of the glass was phase-separation,colorants had no significant effect on microstructure of the glass; with the increase of Al2O3 content,the amount of phosphorus-rich phase was reducing,but the size of the droplets were growing.With the increase of B2O3 content,the size and the distribution of the droplets tend to be homogenize; Al2 O3 improved the water resistance of the glass; B2O3 reduced the water resistance of the glass.
