More Information
Summary:The present invention relates to a method for producing a lead zirconate titanate-based ceramic powder containing uniform, fine lead zirconate titanate, using a solid-phase method. The method includes the steps of mixing a lead oxide powder, a zirconium oxide powder, and a titanium oxide powder to form a mixed base powder; and heat-treating the mixed base powder so that lead oxide in the lead oxide powder and titanium oxide in the titanium oxide powder react to produce lead titanate, and that unreacted lead oxide not used in the reaction, the lead titanate produced by the reaction, and zirconium oxide in the zirconium oxide powder react to produce the lead zirconate titanate-based ceramic powder containing lead zirconate titanate.
