Method for production of dielectric powder

摘要

A dielectric powder consisting of a solid solution of compounds selected at least one each from the two group (a) and (b) of compounds indicated below and having a chemical composition represented by the following general formula: [ABO3]1-x[A'(B'1-yB''Y)O3]x (I) (Wherein x and y satisfy 0<x<1 and 0<y<1 respectively), is produced by mixing metal alkoxides in proportions such that the proportions of the metallic elements thereof conform to the proportions of the metallic elements in the aforementioned general formula (I) and hydrolyzing the metal alkoxides contained in the resultant mixture: (a) Compounds of the ABO3 type perovskite structure and (b) Compounds of the A'(B'1/2B''1/2)O3, A'(B'1/3B''2/3)O3, or A'(B'2/3B''1/3)O3 type valency-compensating perovskite structure (wherein A and A' each denote a divalent metal, B a tetravalent metal, B' a divalent metal or a trivalent metal, and B'' a pentavalent metal or a hexavalent metal).
