Cu//2SO//2 PHASE: ITS PREPARATION AND SOME PROPERTIES.

Article abstract of DOI:10.1007/BF01914544

The conditions of synthesis of the Cu//2SO//2 phase, its thermal characteristics and its reactivity with respect to some other phases occurring in the Cu-S-O system below 710 K, at P//S//O//2 equals 101 kPa, have been given. It has been established that the phase undergoes two reversible solid-state transitions, melts without decomposition at 610 K, and in the liquid state is stable up to 680 K. It is pointed out that Cu//2SO//2 is a phase thermally more stable than Cu//2SO//4.
