Entwicklung einer automatischen Analysenmethode für Industriegipse // Development of an automatic analysis method for industrial gypsum materials
Résumé
The determination of hemihydrate, raw gypsum, and anhydrite in a burned gypsum is inaccurate because the water vapor pressure vs temp. diagram and the stability ranges of the various phases are not known. For this reason a new method for performing this determination by TG is proposed. A special apparatus was designed for the purpose, and its mode of functioning is explained.
