The phenomena of decreasing the catalyst's strength and durability und
er working conditions have been considered. These phenomena have been
treated as a manifestation of the media - catalyst interactions during
catalytical process. The theoretical analysis of micromechanism and c
ontrolling factors and conditions gives one to elaborate the methods o
f essential enhancement of catalyst quality. The rate of surface self-
diffusion is shown to be increased many times due to the appearance of
a great amount of surface adatoms together with interatomic bonds rup
ture. This effect permits to decrease the sintering temperature of pow
der.
