Synthetic approach of ternary magnesium niobate (Mg-Nb-O) compounds.

ABSTRACT: Magnesium based niobium oxides (Mg-Nb-O) were prepared by solid-state reactions owing to understand the function of transition metal oxides as promoters/catalysts for practical application. Magnesium niobate (Mg₃Nb₆O₁₁) was synthesized for the first time in nearly pure form reported in this context. MgNb₂O₆ and Mg₄Nb₂O₉ were prepared in oxidizing conditions; on the contrary, Mg₃Nb₆O₁₁ preferred reducing environment. Stoichiometric mixtures of the precursor materials MgO, Nb₂O₅ and/or metallic Nb were annealed for the syntheses which revealed the effect of temperature on phase formation, reaction kinetics and heat of reaction. The products were exami
