开发了一种用于液相烧结BaTiO3的玻璃，并对其性能进行了测试，以确定使用该玻璃辅助致密化行为的可行性。将玻璃加入到纯BaTiO3粉末中，压制成玻璃含量在4 ~ 20 vol%之间的凹状颗粒。测量了其击穿强度，并与纯BaTiO3和两种市售介质材料进行了比较。液相烧结提高了所有测试成分的纯BaTiO3的击穿强度。与纯BaTiO3相比，添加20 vol%玻璃的样品的击穿强度提高了2.8倍。
A glass used to liquid-phase sinter BaTiO3 was developed and its properties were tested to determine the feasibility of using this glass to aid densification behavior. Glass was added to pure BaTiO3 powder and pressed into dimpled pellets with glass contents varying from 4 to 20 vol%. The breakdown strength was measured and compared with pure BaTiO3 and two commercially available dielectric materials. Liquid-phase sintering increased the breakdown strength of pure BaTiO3 for all the compositions tested. The breakdown strength of the samples containing 20 vol% glass additions was increased by a factor of 2.8 compared with pure BaTiO3.
