【Abstract】 The progress of doping modification of Ba_xSr 1x TiO₃ （Strontium Barium Titanate） materials is reviewed. The effects of various types of dopants such as an acceptor and a donor and concentration of dopants on the dielectric properties are investigated. The relations between composition,microstructure and dielectric properties are discussed.The major problems of doping modification are also presented.更多还原
