Abstract:
1. A method for making a doped magnesium diboride powder, comprising: coating a polymeric precursor on at least one of a plurality of particles of a first phase, wherein the first phase comprises a magnesium diboride powder, the polymeric precursor comprising chemical elements which are configured to yield a second phase, wherein the second phase comprises one or more of a boride, a nitride, a carbide, an oxide, an oxy-boride, an oxy-nitride, an oxy-carbide, or combinations thereof; and heat-treating or cooling, or both, the plurality of particles of the first phase having the polymeric precursor to form a second phase coating onto the at least one of the plurality of particles of the magnesium diboride powder to form a doped magnesium diboride powder.
