Combustion synthesis of nanoscale magnesium borides with improved hydrogen uptake and release
Four MgBx phases have been synthesized: MgB2, MgB4, MgB7, and MgB20. The phase composition depends on the heating time. Combustion synthesis cannot improve the product quality despite the very high heating rate; it also leads to loss of Mg. An effective acid leaching procedure has been identified for removal of MgO. Use of high-purity boron decreases the MgO impurity. First samples have been shipped to the Collaborator for investigating their hydrogenation at Sandia National Laboratories.
