摘要
摘要 热活化与暴露于强不均匀电场的独创组合将多组分溶液转化为前驱体。将气溶胶转化为成品混合物,省去了凝胶形成、长期凝胶干燥和随后的污染研磨等阶段,同时提供了溶胶-凝胶法固有的分子级成分混合。通过同步热分析(STA)研究了批次中的硼酸铋钡部分(0.2Bi2O3-0.6B2O3-0.2BaO)、(Er0.5Y0.5)AG 成分批次和批次前体(最初结合了玻璃陶瓷的所有必要成分)中的相、化学和其他热表现。通过 X 射线粉末衍射 (XRD),确定了在不同温度下由超细批次形成的玻璃陶瓷样品中石榴石和硼酸钇结晶相的形成条件,并利用吉布斯能最小化法确定了这些结晶相的形成条件。
Analysis of Chemical and Phase Transformations during the Synthesis of Glass Ceramics Based on Bismuth Barium Borate Glass and Er:YAG
Abstract
An original combination of thermal activation with exposure to a strong nonuniform electric field transforms a multicomponent solution to a precursor. The transformation of an aerosol into a finished mixture eliminates the stages of gel formation, long-term gel drying, and subsequent contaminating milling, while providing the molecular level of components mixing inherent in the sol–gel method. The phase, chemical, and other thermal manifestations in the bismuth barium borate part (0.2Bi2O3–0.6B2O3–0.2BaO) of the batch, the (Er0.5Y0.5)AG components batch, and the batch precursor, which initially combined all necessary components of glass ceramics, were studied by simultaneous thermal analysis (STA). The Gibbs energy minimization was used to determine the formation conditions of garnet and yttrium borate crystalline phases, identified by X-ray powder diffraction (XRD) in glass ceramic samples formed from ultrafine batches at various temperatures.
