Abstract—T

ransmission electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction analysis have been used to study the structure of superconducting MgB2 ceramics that differ in their contents of alloying elements such as Y and Gd (0.5 and 0.005 wt %). The presence of superfine MgO and Y and Gd boride precipitates was found. The phase composition and sizes of the inclusions and their location in the MgB2 matrix were determined.
