Reduction of polycrystalline and crystalline magnesium orthovanadate Mg3V2O8 by hydrogen was investigated in the temperature range of 560-920°C. A single crystal of orthorhombic Mg3V2O8 with a cation-deficient-spinel structure (25% of the magnesium atoms on octahedral sites are vacant) was transformed into cubic Mg3V2O6 which has a cation-stuffed-spinel structure (8a and 16c sites were partially occupied by magnesium and 16d sites were fully occupied by magnesium and vanadium) at 560°C in 7% H2 in N2.
