| 摘 要： | 采用 TEM、SEM、DTA 和 X 射线衍射等手段研究了 B_2O_3-La_2O_3-ZnO(简称 BLZ)系统玻璃的分相、析晶及其控制。研究指出,BLZ 系玻璃在高硼区有很强的分相倾向易导致析晶。通过引入 BaO 可抑制该系统玻璃的分相倾向,其引入量与 BLZ 系玻璃的组成有关。除此,还研究了 BLZ 系玻璃的析晶与热历史的关系。

| Abstract: | Phase separation and crystallization of B_2O_3-La_2O_3-ZnO (BLZ) glasses wereexamined by TEM,SEM,DTA and X-ray diffraction.It's revealed that thereis a strong tendency to phase separation which leads to crystallization in BLZglasses.When BaO is introduced to BLZ glasses,the tendency of phase separa-tion in BLZ glasses will be suppressed to a certain degree,and the amount ofBaO required depends on the composition of BLZ glasses.The relationship bet-ween crystallization and thermal history of BLZ glasses was also investigated. |
