Abstract

An X-ray and dielectric study of three series of PbNb2O6-type solid solutions was carried out. The PbNbZOs-type phase was present up to the following limits: (1) (Pb1-xBi4/3x)(TixNb2−x·)O 6, ×= 0.2; (2) Pbl-xBi43x)(Ti2Nbl-2)20 6, ×= 0.2; and (3) (Pb1-xBi2/3x)Nb2O6×= 0.3. Orthorhombic distortion b/a and Curie temperature decreased with increasing x. Bi4/3-Ti206 was most effective in this respect and Bi2, 3-Nb2O6 had the least influence. The important role played by ions of different valency located on crystallographically equivalent sites is pointed out
