Thermodynamic properties of Ir2S3 have been obtained from the equilibrium pressures of S2g measured by the effusion technique in the range of 920 to 1110 K. The standard Gibbs energy change at these temperatures for 2 Irs1.5 S2g Ir2S3s was found. The standard heat of formation of Ir2S3 was extrapolated to 25 C. Similar data have been obtained for Ir2S3 0.5 S2g 2 IrS2.
