Abstract
The effects of mechanical grinding on the powder of the YBaCu3O7-delta superconductor (so-called ,,high T(c) superconductor'') were examined . The decrease of the grain size of the powders with the increase of t he grinding time is accompanied by the decrease of the orthorhomibicit y of the unit cells and a decrease of T(c). According to the XRD resul ts the degradation of crystallinity and chemical stechiometricity are the effects of mechanical grinding.
