Abstract :
A MgB2 superconductor was prepared from Mg flakes or powders and B powders using the powder-in-tube technique with explosive consolidation. Compaction of Mg and B powders resulted in a two-phase alloy, due to the relatively low temperature developed during compaction as well as the very short duration of the process. Formation of MgB2 was obtained after subsequent heat treatment in argon atmosphere at a maximum temperature of 950degC.
