Thermal Analysis Study of Antimony Sulfides
Abstract
An investigation of the thermal and oxidative behavior of a series of antimony sulfides was conducted using thermogravimetric analysis, differential scanning calorimetry, high temperature differential thermal analysis, and Fourier transform infrared spectroscopy. Antimony trisulfide was found thermally stable to 575 deg C and oxidatively to 300 deg C, above which it forms cubic Sb2O3. At temperatures above 600 deg C, Sb2O4 is formed. Antimony tri-sulfide undergoes a thermal reaction to produce Sb2S3 between 195 and 230 deg C. Antimony pentasulfide (containing 15 percent excess sulfur) undergoes a thermal transformation to yield Sb2S3 between 193 and 239 deg C. Removal of excess sulfur by extraction has little effect on the thermal or oxidative properties.
