Abstract
Well shaped crystals (cubical or rectangular parallelepiped respective ly, edge length up to 1 mm) of rhombohedral Cr2(SO4)3 can be grown in the less hot zone of a closed silica ampoule by means of CVT using Cl2 or HCl as transport agents in endothermal transport reactions. The in fluence of the mean transport temperature as well as the concentration of the transport agents on the deposition rates was investigated. On the basis of thermochemical calculations an explanation of the transpo rt mechanism is given in the present paper.
