PURPOSE:To provide a dielectric porcelain composition capable of being sintered at a low temp., giving a porecelain high in dielectric constant and excellent in mechanical strength. CONSTITUTION:In a lead base composite perovskite dielectric porcelain composition containing >=50mol% Pb(Mg1/3Nb2/3)O3-PbTiO3, the dielectric composition contains Si of 100-20000ppm in wt. ratio expressed in terms of SiO2 in a composition expressed by a general formula A(ByB'1-y)O3, where A is Pb, B and B' are the same or different di to hexa valent metal, (ByB'1-y) is tetra valent A/B is 0.99-1.00. |
