A novel oxidation catalyst or refractory and the method for its preparation. The material comprises substitutional solid solutions involving MgO, V2O3 and TiO2 and having compositions that fall within a specific polygon in a ternary composition diagram of MgO, V2O3 and TiO2. A typical material has the composition in Wt %; MgO 17, V2O3 61 and TiO2 22, and consists of the phases spinel having the formula Mg1.21V1.58Ti0.21O4 and pseudobrookite having the formula Mg0.20V1.60Ti1.20O5.
