Abstract

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.
