DIELECTRIC PORCELAIN, PROCESS FOR PRODUCTION THEREOF, AND ELECTRONIC PARTS PRODUCED THEREFROM

摘要

A dielectric porcelain comprising TiO2 and ZnO as the principal ingredient and B2O3 and/or B2O3-containing glass as the subsidiary ingredient for realizing the low-temperature sinterability permitting silver, copper or alloys containing silver or copper as the principal ingredient to be used as an inner conductor. It is possible to freely select the temperature coefficient by appropriately selecting the compositional ratio of the principal ingredient and to freely select the sintering temperature by appropriately selecting the content of the subsidiary ingredient. Further it is possible to control crystal structure, relative permittivity, Q-value, temperature coefficient, insulation resistance (IR), and crystal grain diameter by adding oxides of copper, nickel, manganese and silicon in adjusted quantities.
