Method/Apparatus/Procedure:
Static visual cell fitted with magnetic stirrer. Composition og homogeneous phase determined from weighing cell charges at ambient temperature. Details of cell and procedure given in ref. (1). Pressure measured with a pressure balance and temperature measured with Pt resistance thermometer.
Source and Purity of Materials:
(1) Merck sample, purity at least 99.0 moles per cent. Degassed.
(2) Doubly distilled. Conductivity less than 10
