Abstract

Li0.5M0.25TiOAsO4 (M=Mg,Co,Ni,Zn) oxyarsenates powders were prepared by coprecipitation method from dilute solution of Li2CO3,M(NO3)2×H2O (M=Mg,Co,Ni,Zn), (NH4)H2AsO4 and TiCl4 in ethanol. The resulting powders, obtained after drying at about 60 °C, were heated progressively with intermittent grindings at 200 °C–750 °C in air. These new compounds crystallize in the monoclinic system with space group P21∕c. Their parameters are functions of M2+ ion size.
