Several (Ba1-xSrx)TiO3 ceramic powders were synthesized through chemical coprecipitation process, and then (Ba,Sr)TiO3 functionally graded dielectric ceramics were fabricated from these particles by cold compacting and sintering. Their chemical composition, microstructure and dielectric proper-ties were investigated by means of thermal analysis, X-ray diffractometry, electron microscopy and permittivity-temperature test. The results indicate that, the powders exist in cubic (Ba1-xSrx)TiO3 solid solution with nanometer particles. After sintering the grains coarsened somewhat especially for pure BaTiO3, and there were a certain number of pores. The original cubic paraelectric phase transformed partly to tetragonal ferroelectric phase after sintering, and the ferroelectric domains were observed. The graded composition in (Ba,Sr)TiO3 FGM effectively broadened the curie temperature zone and improved their dielectric-temperature stability.
