Abstract:Ceramic pigments of different colour intensities with a perovskite structure on the basis of isomorphously substituted Ва2+in BaTiO3, with element-chromophores: Со3+, Сr3+, Ni2+, Mn2+, Fe3+, Pr3+, Nd3+and Cu2+, are prepared by ceramic technique during solid-state synthesis. The addition of oxides results in different colour gradients. The prepared pigments can be used in the industry for the production of semi-conductive glazes.

Abstract: Classic ceramic technology is the powder method after solid state reactions gadolinium perovskites are sintered; the transition metals are copper Cu, cobalt Co or nickel Ni. These may find applications as semiconductors and as precursors for the preparation of high-temperature superconductors.
