Synthesis of MgB2 from elements
Abstract: Superconducting at 40 K MgB2 -samples were obtained by direct
reaction from elements in molybdenum crucibles under argon pressure. Pressure
allows to provide annealing at temperature up to 1400 oC, that
resulting in rise of Tc and compactness of the ceramics, suggesting
that there is a homogeneity range of composition for the compound.
