化合价的

052 Describes and claims a body of polycrystalline dielectric ceramic material having a lead zirconate--lead titanate--lead stannate composition falling within the area A B C E F of the triaxial diagram 1d of the drawings accompanying this specification and containing at least one substitutional additive ingredient selected from the group consisting of elements having respective ionic radii sufficiently close to the ionic radius of one of the elements lead, tin, titanium, zirconium and oxygen to permit of substitution, and a valence state differing from that of said one element by less than three units, the aggregate quantity of additive ingredient amounting to from 0.1 to 5 percent of the replaced ion on an atom basis, each additive ingredient present in said material being in ionic form and substituting for a finite percentage of the ions of a particular one of the elements lead, tin, titanium, zirconium and oxygen with respect to which it conforms with regard to ionic radius and valence state, said additive ingredient replacing a quantity of said elements having in the aggregate an equal number of valence units.
