  As known, external fields can have a noticeable effect on a number of
processes such as recombination of radicals, processes occurring in biological
systems, some processes of adsorption, etc. However, there are no any mentions
in literature about the impact on chemical processes of non-magnetic and
non-charged bodies which do not have direct contact with the reagents. In the
current study we examine the effect on the hydration of YBa2Cu3O6.75 (YBCO) of
a closely placed non-magnetic and non-charged steel disk. For this purpose we
utilize a previously developed special method of material preparation that has
been published earlier. The resulting material we analyze by the iodometric
titration technique, X-ray diffraction, and X-ray photoelectron spectroscopy.
Conducting the experiment on a large number of the YBCO samples being hydrated
at different distances from the disk clearly indicates a significant inhibitory
effect of this factor. We find that there is a certain distance from the
surface of the metal body, at which the hydration process achieves maximum
sensitivity to the metal presence. At this stage of research, it is assumed
that the mediator, with the aid of which the influence on the hydration process
occurs, might be electromagnetic radiation emanating from the YBCO samples
during their hydration and reflected from the surface of metal.
