A composition for forming a densified dielectric body at low firing temperatures comprising a mixture of particles consisting essentially ofn (a) 95.5-99.4% finely divided wt. of a mixture of metal oxides, metal oxide precursors or polynary oxide reaction products thereof in molar proportions corresponding to the formula (Sr x Pb 1-x TiO 3 ) a (PbMg r W s O 3 ) b , and (b) 4.5-0.6% wt. of a mixture of metal oxides or precursors thereof consisting essentially of (1) a binary oxide of a transition metal selected from the group consisting of Co, Ni, Cr, Mn and mixtures thereof, (2) Cd titanate, Zn titanate or mixtures thereof, and (3) a polynary oxide selected from the group consisting of Cd zirconate, Zn zirconate, Cd stannate, Zn stannate and mixtures thereof. |
