Abstract
A ceramic composition which comprises Pb(Mg1/3Nb2/3)O3 or the oxide precursor thereof, in admixture with barium copper oxide of the formula BaCuO2 as a sinter aid therefor. The compositions do not contain any free lead oxide and have high dielectric constant, e.g. above 8000, and low loss factor, e.g. below 3%.
