COMPLEX OXIDE POWDER, METHOD FOR PREPARING THE SAME, CERAMIC COMPOSITION USING THE COMPLEX OXIDE POWDER AND CERAMIC ELECTRONIC PARTS USING THE CERAMIC COMPOSITION

摘要

A manufacturing method of complex oxide powder is provided to obtain complex oxide powder of which particle diameter is small and crystalline is good using titanium oxide of which a rutilation rate by a line diffraction method is higher than 90% and lower than 100% and a specific surface area is 150 ~ 300 m^2/g. A manufacturing method of complex oxide powder comprises a step of mixing and plasticizing titanium oxide of which a rutilation rate by a line diffraction method is higher than 90% and lower than 100% and a specific surface area is 150 ~ 300 m^2/g and a compound containing a metal element selected in a group consisting of barium, strontium, calcium, magnesium and lead. A determinant diameter of the rutile-type crystal contained in the titanate compound is 10nm or less.
