摘要：

Barium strontium titanate (BST) powders with the different ratios of barium to strontium were synthesized by sol-gel method. The heat treatment system of BST powders, microstructure of BST powders and ceramics were studied. Dielectric properties of BST bulk ceramics, the correlation between curie temperatures and Ba contents of BST ceramics were investigated. The results. show that the BST powders by sol-gel method with much smaller grain sizes (30.58 nm), larger surface areas and better sintering activity can be sintered at 1350 degrees C for 4 h to form ceramics with single perovskite structure.
