Determination of microconcentrations of amphibolic minerals in talc by the method of X-RAY diffractometry

Abstract

An x-ray diffractometry method for determination of amphibole impurities in talc is described. The method is realized on DRON-type diffractometers and allows quantitative evaluation of amphibole at a sensitivity threshold of the instrument in the concentration range of 0.15-4.99%. © 2000 Kluwer Academic/Plenum Publishers
