ABSTRACT:
A porcelain composition comprising Pb(Fe.sub.2/3 W.sub.1/3)O.sub.3, PbTiO.sub.3 and Pb(Yb.sub.1/2 Nb.sub.1/2)O.sub.3 preferably within the range as defined by closed area of A-B-C-D-A in the accompanying triangular diagram can give a sintered product by sintering at a temperature as low as 1000.degree. C. or lower. The resulting sintered product has a high relative dielectric constant and a small dielectric loss tangent.
