Summary

The relationship between microstructures and critical current properties of magnesium diboride (MgB2) bulks was studied. MgB2 bulks synthesized by the solid-solid reaction of magnesium and boron below the melting point of magnesium (650°C) exhibited excellent critical current properties up to high magnetic fields. Low-temperature long-time heat treatment was found to be effective for forming a strongly connected MgB2 matrix with small grain size and poor crystallinity, and a very high critical current was achieved at 20 K.
