Abstract: Most of the dielectric ceramic compositions consist of three or more different lead-based or non-lead ceramics. These materials and their solid solutions can give high dielectric constants (er>10000) but the disadvantage is large fluctuations in the dielectric constant with increasing or decreasing temperature. Most applications of these materials are therefore concentrated on the utilization of their dielectric constants at a specific temperature. This invention provides a dielectric composite of the general formula (x)[Pb(In.sub.1/2Nb.sub.1/2)O.sub.3]:(1-x)[Pb(Mg.sub.1/3Nb.sub.2/3)O.sub.- 3] having improved stability of dielectric constant in the working temperature range.
