Abstract:

Several material science questions involved with growing YBCO quasi-single crystals by the powder melting process (PMP), including the formation of the liquid phase, crystal preferential growth and its controlling, peritectic reaction mechanism and the stability of the front growing interface, size distribution of 211 particles and the formation and controlling of relative defects have been introduced and discussed in the present paper.
