Abstract

A method for quantitative estimation of magnesite in magnesite-rich rocks by differential thermal analysis, using magnesium hydroxide as internal standard, is presented. The effects of variations due to particle size and impurities are discussed.

Résumé

On présente une méthode d'analyse thermique différentielle pour l'estimation quantitative de la magnésite dans des roches riches en magnésite, en utilisant l'hydroxyde de magnésium comme étalon interne. On discute l'effet des écarts dus à la taille des particules et aux impuretés.

Zusammenfassung

Eine differentialthermoanalytische Methode zur quantitativen Abschätzung von Magnesit in magnesitreichen Felsen durch Magnesiumhydroxid als inneren Standards wird beschrieben. Die infolge verschiedener Teilchengrößen und Verunreinigungen auftretenden Schwankungen werden erörtert.
