Abstract A glass with the composition 20.1Na2O•23.1BaO•23TiO2•9.8B2O3•21SiO2•3Al2O3 (in mol%) was synthesized using the traditional glass melting technique. Its thermal properties were characterized by differential thermal analysis (DTA) and appropriate time-temperature schedules were applied in order to prepare glass-ceramics containing barium titanate. Analysis by X-ray diffraction (XRD) showed the formation of cubic barium titanate and fresnoite for the annealing temperature of 650 °C and times t ≥ 3h, while annealing for 1 h resulted in the sole crystallization of barium titanate. Supplying longer crystallization times resulted in the additional formation of increasing fresnoite concentrations. The crystallization behavior of the glass is characterized using electron microscopic techniques, i.e. energy dispersive X-ray spectroscopy (EDXS) and electron backscatter diffraction (EBSD) which reveal the simultaneous growth of fine, densely-branched barium titanate and fresnoite crystals.

组成为20.1Na2O•23.1BaO•23TiO2•9.8B2O3•21SiO2•3Al2O3的玻璃中钛酸钡和弗氏体的结晶和生长形态

摘要采用传统的玻璃熔炼技术，合成了成分为20.1Na2O•23.1BaO•23TiO2•9.8B2O3•21SiO2•3Al2O3的玻璃。通过差热分析（​​DTA）表征其热性能，并应用适当的时间-温度程序以制备含钛酸钡的玻璃陶瓷。X射线衍射（XRD）分析表明，在650°C的退火温度和t≥3h的时间下，形成了立方钛酸钡和马氏体，而退火1 h则导致钛酸钡的唯一结晶。提供更长的结晶时间会导致形成额外的增加的方铁矿浓度。玻璃的结晶行为使用电子显微镜技术进行表征，即
