SUMMARY
The discussion focuses on measuring the conversion of silicon (Si) to silicon dioxide (SiO2) in a powder mixture containing Si, SiO2, Fe3O4, FeO, and Fe. A Thermo Gravimetric Analyzer (TGA) is recommended as the instrument for this analysis, capable of operating at temperatures up to 1500 degrees Celsius. By utilizing the evaporation temperatures of each component and monitoring weight loss during the heating process, one can accurately determine the composition of the powder.
