The claim that the high-temperature equilibium tetragonal Nb3Si phase can be transformed, by explosive compression, into a superconducting phase has been confirmed. After being subjected to shock compression with peak pressure close to 1 Mbar, the resulting material is superconducting, with an onset Tc of 18 K. The structure of this superconducting phase is ambiguous, but it could have the A15 structure with a lattice parameter of 5.12 Å.
