A series of polycrystalline samples of SrMo1-xNixO4(0.02<=x<=0.08) were prepared through the conventional solid-state reaction method in air. Appropriate proportions of high-purity SrCO3, MoO3, and Ni powders were thoroughly mixed according to the desired stoichiometry, and then prefired at 900 [ ?]C for 24 h. ?]C for 24 h with intermediate grinding twice. White compounds, SrMo1-xNixO4, were obtained. The compounds were ground and pressed into small pellets about 10 mm diameter and 2 mm thickness.
