"In the work the laws of copper oxide, CuO, reduction by hydrogen to
metallic copper under the self-propagating mode have been studied,"
investigators in Yerevan, Armenia report (see also Alloys and
Compounds).

"It was shown that reduction process may be performed under the
combustion mode even at low hydrogen pressure 0.01 MPa. At constant
hydrogen pressures the reduction of samples prepared from initial
copper oxide occurred under the surface combustion regime resulting
in non-uniform Cu/CuO product, followed by complete reduction of the
oxide," wrote M.H. Yamukyan and colleagues.

The researchers concluded: "The results of researches have allowed to
determine the main factors influencing on the basic characteristics
of combustion process."

Yamukyan and colleagues published their study in the Journal of
Alloys and Compounds (Copper oxide reduction by hydrogen under the
self-propagation reaction mode. Journal of Alloys and Compounds,
2009;473(1-2):546-549).
