transition alumina

Thick films with a thickness of 10 μ m on Pd/ Ag electrode alumina substrates also show the characteristic of diffused phase transition by the spin coating technique.

用匀胶法制备的沉积在Pd/Ag电极上的BST厚膜，膜厚约为10μm，也呈现明显的弥散相变特征。

The reaction behavior, phase transition and microstructure of the membrane were investigated by different techniques, such as thermogravimetric analysis, energy dispersive spectroscopy, X ray diffraction, thermomechanical analysis and scanning electron microscopy. The structure of alumina hollow fiber membrane is asymmetrical.

采用热重分析、能量色散谱、X射线衍射、热机械分析和扫描电镜等手段对烧结过程中的反应行为、相转变及膜的微观结构进行了研究。

Ba ( NO3) 2 were chosen as a thermal stabilizer in order to retard the V-alumina phase transition into a-alumina in high temperature.

选用Ba（NO3）2作热稳定剂希望能够使得氧化铝高温时仍具有高比表面积。
