IR Study of the Transformation of WF6 on a W Substrate

Autor: V. V. Dushik, R. Kh. Zalavutdinov, N. V. Rozhanskii

Publikováno v: Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques. 13:919-924

A new IR-spectroscopy (infrared) technique allowing investigation of the transformation of gaseous WF6 on a W surface heated up to 860 K in a hydrogen and argon atmosphere is proposed. The weak chemical adsorption of WF6 on W substrates is observed.
