PURPOSE:To obtain the title composition having high dielectric constant, insulation resistance and small change of dielectric constant with temperature in production of the title composition of perovskite type shown by the formula ABO3 containing Pb and Ba as a component A by using at least a specific BaTiO3 as a raw material. CONSTITUTION:In production of the title composition of perovskite type shown by a general formula ABO3 containing Pb and Ba as a component A, BaTiO3 powder which is produced by hydrothermal synthetic method or glass crystallizing method and has >=50wt.% BaTiO3 powder having 1-3m<2>/g specific surface area is at least used as a raw material. |
