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.
