Lead-lanthanum zirconate-titanate (PLZT) powders were prepared by molten salt synthesis and solid state reaction. PLZT powder formation in the presence of fused salt was completed at lower temperature than that in solid state reaction, and the particle size of the powder increased markedly with increasing heating temperature. The dielectric, piezoelectric and optical properties of both ordinary fired and hotpressed PLZT ceramics fabricated from these powders were investigated. The electromechanical coupling factor and optical transmittance of PLZT ceramics from molten-salt-synthesized powders were smaller than those from solid state reaction, probably due to the substitution of Na and K ions (in NaCl-KC1) for Pb ion in PLZT ceramics.
