采用溶胶-凝胶法制备适合Al 2 O 3、AlN陶瓷基板厚膜浆料用BaO-ZnO-B 2 O 3-SiO 2(BZBS)系无铅低熔玻璃粉。研究了pH值、温度对凝胶化过程的影响，并通过TG-DSC、XRD、SEM等手段分析了玻璃粉体性能、结构及形貌变化。结果表明：溶胶-凝胶法得到的BZBS玻璃粉经500℃热处理后其主要物相组成为非晶玻璃相和少量微晶，析出的主要晶相为BaCO 3以及少量Ba(CO 3)0.9(SiO 4)0.1和ZnO。溶胶-凝胶法制备的BZBS玻璃粉经850～900℃热处理，不仅能与Al 2 O 3陶瓷基板，还能与AlN陶瓷基板形成很好的润湿，可以作为陶瓷厚膜金属化电子浆料用玻璃粘结剂。

A new type thick-film paste of BaO-ZnO-B2O3-SiO2(BZBS) lead free glass binder was prepared by a simple sol-gel approach, which can be used on Al2O3 and AlN ceramic substrates. The effects of pH value and temperature on the gelation process were investigated. The chemical features, structure and morphology of the as-prepared samples were characterized by TG-DSC, XRD and SEM. The results show that main crystalline phase of the BZBS glass is indexed to BaCO3 while still presented a tiny of Ba(CO3)0.9(SiO4)0.1 and ZnO after heating at 500℃. After heating above 850℃,the glass powder exhibites the excellent wetting properties on both Al 2 O 3 and AlN ceramic substrates, which indicates that the glass system can be used as glass binder of electronic pastes suit for thick film ceramic metallization.
