Abstract
Li1 − 3xFexNiPO4 (0 < x < 0.15) solid solution phases have been synthesized by solid state reaction. X-Ray studies on polycrystalline samples show that all phases are isostructural with the parent LiNiPO4 compound, crystallizing in the orthorhombic system, space group Pnma. The evolution of the lattice parameters with the iron content follows Vegard's law. The
