During calcination, the primary intermediate compound is pyrochlore phase in the Pb(Ni1/3Nb2/3)O3-rich composition, while it is PbZrO3 on the PbZrO3-rich side. On calcination at 800¢XC, all precursors convert into perovskite phases. In the formed solid solutions, increasing PbZrO3 content results in a rise in the apparent Curie temperature as well as the maximum dielectric permittivity. The Pb(Ni1/3Nb2/3)O3-rich perovskites (x < 0.8) possess the characteristics of relaxor ferroelectrics. With increasing PbZrO3 content, the dielectric response gradually becomes less diffuse and dispersive, reflecting a reduction in the relaxor characteristics of the formed perovskites.[SDGs]SDG6journal article10.1557/JMR.1999.01862-s2.0-0032677379https://www.scopus.com/inward/record.uri?eid=2-s2.0-0032677379&doi=10.1557%2fJMR.1999.0186&partnerID=40&md5=7ab72a6ba9f8f2b180366bbcfb724115
