PURPOSE:To obtain ceramic powder having electro-optical characteristics, by blending a mixed solution of lead nitrate, lanthanum nitrate and zirconium nitrate with a precipitate-forming solution, coprecipitating metallic components, adding a solution of titanium alkoxide to the precipitate to blend and to coprecipitate them. CONSTITUTION:A mixed solution of lead nitrate, lanthanum nitrate and zirconium nitrate is prepared, the mixed solution is blended with a precipitate-forming solution and metallic components are coprecipitated. Further the precipitate is mixed with a solution of titanium alkoxide and coprecipitated. The precipitate is dried and calcined at 400-1,200 deg.C to produce ceramic powder containing Pb, La, Zr and Ti as active ingredients. |
