Abstract

We report a novel high-pressure coupling (HPC) reaction that couples the nitridation of Re with high-pressure solid-state metathesis (HPSSM) of Fe3N to produce a spherical bulk RexN/Fe3N composite. Compared with conventional methods, upon coupling of the HPSSM reactions, the synthetic pressure for Re nitridation was successfully reduced from 13 to 10 GPa (for Re3N) and from 20 to 15 GPa (for Re2N). The product RexN species would be surrounded by product Fe3N, resulting in a spherical bulk RexN/Fe3N composite (x = 2 or 3). The composite exhibits a soft magnetic behavior, and the content of nitrogen in RexN (x = 2 or 3) was controlled by adjusting the P-T conditions. The HPC reaction establishes a new approach for the bulk synthesis of 5d transition metal nitride.
