The thermal stability and crystallization behaviors of La₂O₃ containing B₂O₃-CaO–Al₂O₃ glass waste forms were investigated to evaluate the stability of waste form during emergencies in deep geological disposal. For glasses containing 15% La₂O₃, LaBO₃ phases were observed as major crystals from 780 °C and exhibited needlelike structures. Al, Ca, and O were homogeneously distributed throughout the entire specimen, while some portions of B and La were concentrated in some parts. By differential thermal analysis at various heating rates, the activation energy for grain growth and the crystallization rate of LaBO₃ were calculated to be 12.6 kJ/mol and 199.5 kJ/mol, respectively. These values are comparable to other waste forms being developed for the same purpose.

研究了含La ₂ O ₃的B ₂ O ₃ -CaO-Al ₂ O ₃玻璃废料的热稳定性和结晶行为，以评估深部地质处置紧急情况下废料的稳定性。对于含有 15% La ₂ O ₃、LaBO _{3 的}玻璃在 780 °C 时观察到作为主要晶体的相，并表现出针状结构。Al、Ca 和 O 均匀分布在整个样品中，而 B 和 La 的某些部分集中在某些部分。通过不同加热速率下的差热分析，计算出LaBO _{3 的}晶粒生长活化能和结晶速率分别为12.6 kJ/mol和199.5 kJ/mol。这些值与为相同目的而开发的其他废物形式相当。
