摘要：

Synthesis of cobalt nitrides has been tried in a supercritical nitrogen fluid at high pressure (about 10 GPa) and high temperature (about 1800 K) using diamond anvil cell and YAG laser heating system. We have succeeded to synthesize a single phase of the CFe2-type Co2N easily in a short time. This is the first synthesis by a simple reaction between the pure cobalt and pure nitrogen (supercritical fluid nitrogen). The cell parameters of the synthesized Co2N are a=4.662(9) angstrom, b=4.332(5) angstrom and c=2.749(9) angstrom, respectively. (c) 2005 Elsevier Ltd. All rights reserved.
