Thermogravimetrische Untersuchungen an zeolithischen Erdalkalithioferraten(III)

摘要

The degradation of the hydrates of the alkaline earth thioferratesM(FeS2)2·xH2O,M=Ca, Sr, Ba, resulting from ion exchange on KFeS2, is studied by TG and by X-ray diffraction analysis. The zeolitic character of the very loosely bound water in these compounds is proved. There exist several cristallographically distinct phases as a function of the water content
