Synthesis of MgB2 from Mgb4 through combinatorial solid state reaction routes.

MgB4 was first prepared from the elemental magnesium and boron powders, followed by acid-washed in order to remove the primary impurity of MgO. In the second step, appropriate amount of Mg was added into the MgB4 powders and sintered in the temperature range of 650°C to 950°C for 8 hours. XRD spect...
