摘要：
Crystals of PtCl//3 are obtained from the vapor phase in closed fused silica ampoules at temperatures near 785 K and at a chlorine pressure of about 26 atm. The thermodynamic parameters characterizing the single-phase field of solid PtCl//3 are determined. The growth of the crystals results from vapor transport which is a combination of a sublimation and two dissociative reactions. The complex transport is investigated using the solubility theory of Schaefer. The theory reveals an increase in the transport rate with increasing chlorine pressure when the source is heated to the temperature which separates the fields of solid PtCl//2 and PtCl//3.
