A New Route for the Synthesis of MoN

The Molybdenum nitride was synthesized by the reduction of Molybdenum dioxide with ammonium chloride under extreme conditions of high pressure and high temperature. The product was examined with XRD measurement. The results show that the MoN has the hexagonal symmetry with lattice constants of a=0.572 nm, c=0.560 nm, and space group of P63/mmc. The Mo atoms are at the positions 2b (0, 0, 1/4) and 6h (x, 2x, 1/4), x=0.489, the N atoms are at the positions 2a (0, 0, 0) and 6g (0.5, 0, 0). This method is very easy to be attached, and get the pure phase, as well as need a short time to react.
