Abstract

The crystal structure and dielectric propoerties of $(Pb_{1-x}Ca_x)(Zr_{1-y}Sn_y)O_3$ Ceramics were investigated. Sn substitution reduced the volitility of PbO due to the decrease of the unit cell. The crystal structure of $(Pb_{1-x}Ca_x)(Zr_{1-y}Sn_y)O_3$ Ceramics was refined based on Orthorhombic Cmmm space group, More than two types of phase transition were observed, These phase transitons make the posicitve and negative temperature coefficient of dielectric constant of $(Pb_{1-x}Ca_x)(Zr_{1-y}Sn_y)O_3$.
