ZnO含量对Li2O-ZnO—SiO2玻璃析晶及性能的影响
Effects of ZnO content on the crystallization and property of Li2O-ZnO-SiO2 glass
摘要
Abstract
We addressed the effects of different ZnO content on the crystallization behavior and property of the Li2O-ZnO-SiO2 glass system with differential scanning calorimeters （DSC）, x-ray diffraction （XRD） and scanning electronic microscope （SEM）. Experimental results show that its precipitated phases are cristobalite, tridymite, Li2SiZnO4and SiO2. The relative cristobalite content initially increases and then decreases with the increase of ZnO content The cristobalite phase influenced thermal expansion coefficient α also initially increases and then decreases. The relative cristobalite content reaches the highest value when the ZnO content arrives at 21. 1%. Its thermal expansion coefficient reaches the maximum value of 19.13 × 10^-6/℃ when the ZnO content arrives at 26.7%.关键词
