Abstract

We report the study of the polycrystalline MgB2 phase formation during the fabrication processes. Three major phases are identified in different sintering temperature ranges according to the corresponding superconducting properties and the crystalization conditions. The optimum fabrication parameters are obtained for the MgB2 superconducting phase formation.
