SYNTHESIS OF SUPERCONDUCTING MAGNESIUM DIBORIDE OBJECTS

WIPO Patent Application WO2002064859

A3

A process to produce magnesium diboride objects (210) from boron objects (204) with a similar form. Boron objects (204) are reacted with magnesium vapor at a predetermined time and temperature to form magnesium diboride objects (210) having a morphology similar to the boron object's original morphology.
