PROBLEM TO BE SOLVED: To obtain a dielectric raw material powder used for producing a dielectric ceramic composition, to provide a method for controlling the particle diameter thereof, and to obtain a dielectric ceramic by using the raw material powder. SOLUTION: The change of the particle diameter of a powder based on the change of a calcining temperature is reduced by allowing 1 mol BaTiO3 type raw material powder represented by the formula A.B.O3 to include 0.05-2.0 mol.% Cl, and the powder having a homogeneous particle diameter is obtained. A dielectric ceramic product having good characteristics can be produced by producing the dielectric ceramic product by using the raw material powder produced by the method. |
