PURPOSE:To obtain a nonreducible dielectric porcelain compsn. having high insulation resistance even by firing in a reducing atmosphere. CONSTITUTION:This dielectric porcelain compsn. is represented by a formula (Ba1-xSrxO)mTiO2 (where 0<=x<=1.0 and 1.005<m<=1.04) and contains <=400ppm (expressed in terms of Nb2O5) Nb. |
