Instrument or method to analyze Si and SiO2 powder

Click For Summary
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.

PREREQUISITES
  • Understanding of Thermo Gravimetric Analysis (TGA)
  • Knowledge of evaporation temperatures for Si, SiO2, Fe3O4, FeO, and Fe
  • Familiarity with powder composition analysis
  • Basic principles of thermal analysis techniques
NEXT STEPS
  • Research the operational principles of Thermo Gravimetric Analyzers (TGA)
  • Study the evaporation temperatures of Si, SiO2, Fe3O4, FeO, and Fe
  • Explore methods for calculating weight loss during thermal analysis
  • Investigate alternative methods for powder composition analysis
USEFUL FOR

Chemists, materials scientists, and researchers involved in powder analysis and thermal characterization of materials will benefit from this discussion.

Hii...

I have a powder that consists of Si, SiO2, Fe3O4, FeO and Fe. I really want to measure the conversion of Si to SiO2. Anybody know what kind of instrument or method that can be used to measure the composition?

I really want to measure the conversion
I thing you mean Yield.

I have an idea it may works but it is not accurate.
If you have evaporation temperature for every component you can insert your sample in Thermo Gravimetric Analyzer which is an instrument that calculate change in weight vs temperature and it can go up to 1500 degree celsius. Now,by knowing evaporation temperature for every component and weight loss during heating process then you can find the weight of every component.
