Vapor pressure measurements in the homogeneity range of the Ti1 + xS2 (x = 0.015–0.090) phase

The equilibrium vapor pressure over the Ti 1 + x S 2 ( x = 0.015–0.090) phase has been measured in the temperature range 762–1208 K by a static method using a quartz membrane null-manometer. The measurement results were used to construct ( p – T ) x = const contours of constant composition at x valu...

Summary:The equilibrium vapor pressure over the Ti 1 + x S 2 ( x = 0.015–0.090) phase has been measured in the temperature range 762–1208 K by a static method using a quartz membrane null-manometer. The measurement results were used to construct ( p – T ) x = const contours of constant composition at x values in the range from 0.022 to 0.060. Relevant data in the literature have been critically evaluated with the aim of identifying the most reliable data. The crystal structure of Ti 1.015(2) S 2 has been determined. The X-ray structure analysis results indicate the presence of excess titanium in the interlayer spaces of the structure.
