A series of fluorochlorozirconate (FCZ) glasses, each doped with a different rare-earth, was prepared and examined to determine thermal stability and activation energy, Ea , of the dopant dependent BaCl2 crystallization. Non-isothermal differential scanning calorimetry (DSC) measurements were done to investigate the endothermic and exothermic reactions upon heat treatment of the glass samples. In comparison to the rare-earth free FCZ glass, significant changes in the Hruby constant, Hr , and Ea were found due to the addition of a rare-earth and also between the individual dopants.

稀土掺杂氟氯锆酸盐玻璃的结晶行为。

制备并检查了一系列氟氯锆酸盐 (FCZ) 玻璃，每一种都掺杂了不同的稀土，以确定掺杂剂依赖的 BaCl2 结晶的热稳定性和活化能 Ea。进行非等温差示扫描量热法 (DSC) 测量以研究玻璃样品热处理后的吸热和放热反应。与不含稀土的 FCZ 玻璃相比，由于添加了稀土以及在各个掺杂剂之间，发现 Hruby 常数、Hr 和 Ea 发生了显着变化。
