Ceramic dielectric compositions which have dielectric constants above 100, dissipation factors of less than 0.1 percent, and temperature coefficient characteristics of less than 150 ppm/ DEG C. The dielectric compositions are also sinterable at temperatures below 1,140 DEG C. Said compositions comprising about 84,7 to 86,4 % of a precursor material and 13.61 to 15.3 % of a frit composition, the precursor material comprising principally about 52,08 to 55,03 % neodymium oxide, 28,76 to 29,88 % titanium oxide, 8,32 to 11,15 % lead oxide, and 6,61 to 8,69 % barium oxide, the frit composition comprising about 10,00 to 10,20 % bismuth titanate, 2,35 to 4,35 % lead oxide, 0,28 to 0,70 % silicon oxide, 0,25 to 0,26 % niobium pentoxide, 0,09 to 0,50 % boron oxide, and 0,1 % manganese carbonate. |
