Abstract

A quantitative method is presented for the estimation of calcite in limestones by differential thermal analysis, using calcium hydroxide as an internal standard. The effects of variations due to particle size and impurities such as quartz, iron oxide, organic material, dolomite, magnesite, gypsum and phosphates are discussed.

Résumé

On propose une méthode de dosage par ATD de la calcite dans les roches calcaires en utilisant l'hydroxyde de calcium comme étalon interne. On discute l'influence de la taille des particles et de la nature des impuretés: quartz, oxyde de fer, corps organiques, gypse, dolomite, magnésite et phosphates.

Zusammenfassung

Es wurde eine quantitative Methode zur Ermittlung von Kalzit im Kalkstein durch Differentialthermoanalyse unter Anwendung von Kalziumhydroxyd als inneren Standard vorgestellt. Der Einfluß von durch unterschiedliche Teilchengröße und Verunreinigungen, wie Quarz, Eisenoxyd, organische Stoffe, Dolomit, Magnesit, Gips und Phosphat hervorgerufenen Veränderungen wurde erörtert.

Резюме

Описан количественн ый метод определения кальцита, находящего ся в карбидах методом дифференциа льного термического анализа с использова нием гидроокиси кальция в качестве вн утреннего стандарта. Обсуждены принципы о тклонений, к которым относятся ра змер зерна и такие заг рязнения как кварц, окись желез а, органические вещества, доломит, маг незит, гипс и фосфаты.
