Abstract
Differential thermal analysis is studied as a quantitative method due to the need for a technique as an alternative to X-ray diffraction analysis, where interferences, costs, and certain difficulties with very small samples are a problem. For thermal analysis, particle size of settled dusts or "grab" samples is determined by a combination of mechanical classifying and microscopic techniques. Procedures are developed for determining quartz (1317799) in samples where there is no single predominant size range. Grinding time and sample weight are controlled and the X- ray diffractometer is used to monitor size reduction.
