Synthesis of double oxide NiTiO₃ using dissolution phenomena of titanium and nickel

Abstract

Attempts have been made to synthesize nickel titanate (NiTiO₃) using dissolution of nickel and titanium. The powders obtained by calcinating the mixture corrosion products at a temperature more than 873 K was identified as NiTiO₃ by XRD analysis. The NiTiO₃ powders which obtained after the calcination at 1473 K had the diameters from 0.4 to 6.5 µm, and a median of the size distribution of 2.3 µm. Preparation of NiTiO₃ using corrosion synthesis is discussed from the viewpoint of electrochemistry.
