ZrSn0,5Ti0,5O4 als Wirtsstruktur für keramische Farbkörper Strukturuntersuchungen an ZrTiO4 und ZrSn0,5Ti0,5O4

ZrSn_0.5Ti_0.5O₄ as a Matrix for Ceramic Colours. Structural Investigations on ZrTiO₄ and ZrSn_0.5Ti_0.5O₄ ZrSn_0.5Ti_0.5O₄ and ZrTiO₄ crystallize in Pbcn having the lattice constants a = 481.45(10), b = 559.61(11), c = 510.50(9) pm and a = 478.55(13), b = 547.55(12), c = 502.77(14) pm, respectively. Their crystal structures have been solved and refined using single crystal data. According to the structural data derived in this work ZrTiO₄ possesses α-PbO₂ type of structure with Zr and Ti randomly distributed over the cation sites. ZrSn_0.5Ti_0.5O₄ is isostructural. As compared to ZrTiO₄ the metal-oxygen bond lengths in ZrSn_0.5Ti_0.5O₄ are increased. By substituting M⁴⁺ by In³⁺ (RE³⁺) and V⁵⁺ bright yellow pigments have been obtained.
