摘要：
The (Ba1-xSrx)TiO3 ceramic solid solution in the range 0.3 <= x <= 0.5 was prepared by the sol-gel method. Barium acetate, strontium acetate and tetra-butyl titanate were used as starting materials. Thermal evolution of the dried gel as well as ceramic powder was studied by simultaneous thermal analysis. The amorphous gel of BST was calcined in the furnace and pressed into pellets. The compacts were next sintered by free sintering method at temperature T=1450 degrees C. The structure, microstructure and dielectric properties were studied for sol-gel derived ceramics.
