稀土氧化铈对玻璃陶瓷晶化及性能的影响

Effect of rare earth CeO_2 added on crystallization and properties of a glass-ceramic

采用DTA、XRD和SEM等现代测试手段探讨了稀土氧化铈对CaO-MgO-Al_2O_3-SiO_2系统玻璃陶瓷晶化及性能的影响。研究结果表明:添加适量的氧化铈有利于改善玻璃液的澄清效果,消除气泡,使玻璃结构紧凑,材料力学性能和耐碱性均有所提高。氧化铈最佳的添加量为1.5％。图3,表2,参9。

This paper analyses the effect of different amount of CeO2 added on crystallization of CaOMgO-Al2 O3-SiO2 system glass and material properties with the aid of differential thermal analysis, X-ray diffraction and scanning electron microscopy,and results indicate that a suitable amount of CeO2 added could improve clarifying action of glass fluid,eliminate air bubble,increase alkali resistance and physical and mechanical properties,and material structure become more compact optimal amount of CeO2 was 1. 5wt%. 3figs. ,2tabs. ,9refs.
