Production of nickel zirconate-based pigments having perovskite-like structure using sedimentation

The processes of joint hydroxide deposition of nickel (II) and zirconium (IV) with the production of nickel zirconate have been investigated. During the subsequent heat treatment of hydroxides at a lower temperature compared to powders, stabilized nickel zirconate with a stable crystal lattice is formed, in which Zr ⁴⁺ ions are replaced by Ni ²⁺ ions to obtain a colored connections. This serves as a prerequisite for the synthesis of stable pigments with a perovskite-like structure. Tab. 1, ill. 3, bibliography: 6 titles.
