Abstract
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(9) nm, c=0.560(4) nm, and space group of P6(3)/mmc. The Mo atoms are at the positions 2b(0,0,1/4) ...
Abstract
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(9) nm, c=0.560(4) nm, and space group of P6(3)/mmc. The Mo atoms are at the positions 2b(0,0,1/4) and 6h(x,2x,1/4), x=0.48(9), The N atoms are at the positions 2a(0,0,0) and 6g(0.5,0,0). This method has many advantages: the reaction condition is very easily carried out, the product is pure phase, and the reaction time is short. (C) 2000 Elsevier Science S.A. All rights reserved.
