Abstract
A device for measurement of sulfur fugacities of single crystals of sulfides at elevated temperatures was designed for use with a precession camera and successfully employed in studies of pyrrhotite. The device contains the solid-state electrochemical cell Pt, Ag(s)|AgI(s)|Ag2S(s), S2(g), Pt and enables simultaneous determination of temperature, sulfur fugacity, and crystal structure. Trial studies confirmed that the stable pyrrhotite structure at 437°, 434°, and 320°C is the 1C type. Measured sulfur fugacities for the crystals are slightly lower than calculated values from earlier data.
