Popis:	The influence of the temperature and its gradient on powder features and defect formation is discussed in the light of experimental results in the physical vapour transport process. The recrystallization of the source powder during crystal growth appears to be directly related to the temperature gradient field within the source material. Moreover, several calculations made on different experimental geometries of crucible show that the location of the macrodefects is strongly related to the temperature gradient in the crystal. Technical solutions in order to avoid or reduce the macrodefects formation are discussed.
