(BaxSr1-x)(Zn1/3Nb2/3)O3 complex perovskite ceramics produced by reaction-sintering process were investigated. Secondaryphases ZnNb2O6 and (Cu2Zn)Nb2O8 were found at the perovskite matrix grain boundaries. 98.5–99.8% of the theoretical densitywas obtained. In (Ba0.5Sr0.5)(Zn1/3Nb2/3)O3 and (Ba0.7Sr0.3)(Zn1/3Nb2/3)O3, the amount and volume of second phases decreasedclearly at 1500℃.
