Abstract
The report describes the amorphization occurring during mechanical grinding of a mixture of Bi-HTSC 2223 and 2212 phases. It is shown that the visually determined grain size and the actual crystal size diminish upon grinding. Noticeable amorphization occurs even after only 30 min of grinding. Furthermore, different crystal planes exhibit variable sensitivity towards the amorphization process and the high T c-phase is more easily affected by this phenomenon than the low T c-phase in the Bi-system. Identical results were obtained whether the starting composition of the spray dried powder was 2223 or 2234
