Abstract
Dielectric ceramic compositions of the ferroelectric type, especially for the fabrication of multilayer ceramic capacitors having improved properties, contain 90% to 98.5% by weight of barium titanate and 1.5% to 10% by weight of lithium fluoride, in which the barium titanate corresponds to the following formula: PA1 BaTiO.sub.3 with a molar ratio TiO.sub.2 /BaO which is lower than 1.
