Abstract:
Superhard superconducting samples with a critical temperature of $T_c=12.6\,$K are obtained when synthetic diamond powders that were preliminarily coated with a niobium film are sintered at a pressure of 7.7 GPa and a temperature of 1973 K. Superhard superconductors with $T_c=9.3\,$K are obtained when diamond and molybdenum powders are sintered at a pressure of 7.7 GPa and a temperature of 2173 K. Superconducting samples with $T_c=36.1\div 37.5\,$K have been obtained in the systems diamond–MgB$_2$ and cubic boron nitride–MgB$_2$.
