The effect of synthesis and postgrowth treatment (by annealing at various temperatures and partial oxygen pressures) conditions on structural homogeneity of YBa 2 Cu 3 O x single crystals has been studied. The obtaining of single crystals with both high oxygen content and high critical temperatures T c has been optimized. The wide range of postgrowth treatment conditions proposed allows to receive single crystals with given oxygen content from 6.2 to 7.0.
