Title

Formation mechanisms of (metastable) copper, nickel and vanadium nitrides through in-situ neutron diffraction of solid-gas-reactions

Abstract

In-situ neutron diffraction can provide valuable information on phase formation mechanisms in solid state. We have developed an in-situ neutron diffraction cell, suitable for studies of solid-gas reactions under flowing gas conditions at higher temperatures, for the study of metastable nitride formation. Experiments will be performed under flowing ammonia. Heating will be realized by a laser heating system. The equipment was successfully tested within LTP-5A-1 in cooperation with Dr. Kohlmann (Univ. Saarland, Germany). Interesting systems for in-situ measurements are Cu–N, Ni–N and V–N because only partly known intermediate stages are involved in formation of nitride phases. Intermediates are visible through colour changes during the reaction. An exact knowledge on formation mechanisms of such materials will provide a successful approach for a customized synthesis.
