Abstract

Tc metal and metal-like carbide phases are revisited with special attention given to Tc-rich phases in the view of prospective nuclear fuel utilization and alternative transmutation targets fabrication. A new Tc-metal phase has been found and new softer conditions for the Tc carbide formation were observed. The unit cell parameters of a new orthorhombic Tc metal were a = 2.805 (4), b = 4.958 (8), c = 4.474 (5) Å (V/z = 15.55Å³) for Tc-C with 1.38wt. % C and a = 2.815 (4), b = 4.963 (8), c = 4.482 (5) Å (V/z = 15.65 A³) for Tc-C with 1.96 wt. % C.
