| Abstract: | Superconducting compounds, such as cubic  -MoC1–x, cubic  -WC1–x, hexagonal MoB2, and cubic  -TaN, which are metastable at room temperature, have been formed by heating and quenching of their respective equilibrium phases, such as hexagonal  -MoC1–x, hexagonal WC, rhombohedral Mo2B5, and hexagonal  -TaN in a plasma jet. From calculations based on a simple model, the quenching rate of particles has been estimated to be 105 deg s–1. |
