摘要:PROBLEM TO BE SOLVED: To obtain a dielectric porcelain composition capable of being fired at a relatively low temperature and having a high relative dielectric constant and a low dielectric tangent. SOLUTION: Pb(Mg1/3Nb2/3)O3 and PbTiO3 are used as principal components. The proportion of the Pb(Mg1/3Nb2/3)O3 is 90.0-97.0 mol% and that of the PbTiO3 is 3.0-10.0 mol%. BaTiO3 is added as a subsidiary component to the principal components by 0.1-5 pts.wt. based on 100 pts.wt., in total, of the principal components.
