Abstract

Compositions in the perovskite family, having the general formula Pb(B//1, B//2)O//3 and known as ferroelectric relaxors are of considerable interest. Their high dielectric constants, broad maxima, and relatively low firing temperatures have made them promising candidate materials for multilayer ceramic capacitors. However, such materials are difficult to fabricate reproducibly without the appearance of a pyrochlore phase that can be detrimental to the dielectric properties. Recent work on the kinetics and thermodynamics of the perovskite vs pyrochlore formation is reviewed. Such an understanding will enable the implementation of relaxor dielectrics into the current multilayer capacitor industry.
