Sažetak

CdS-MnS systems obtained by coprecipitation from aqueous
solutions of corresponding sulphates by ammonium sulphide were
dried for months over Silicagel and then submitted to thermogravimetric
analysis. Their content of water and of excess
sulphur passes through minima in the critical zone of precipitation,
where the precipitates contain very nearly 0.1 mol O/o MnS. It
is believed that the minima correspond to a minimum of specific
surface of the precipitates and that this minimum separates the
region of formation of CdS : MnS solid solutions from the region
towards greater contents of MnS, where coprecipitation of the
saturated solid solution CdS : MnS and MnS occurs.
