PREPARATION OF Ag4Sn3S8 COMPOUND IN AgNO3-SnS2-C2H4(OH)2 SYSTEM

The conditions for producing Ag4Sn3S8 compound in ethylene glycol medium are investigated by X-ray fluorescence (XRF), differential thermal (DTA) and electron microscopic analysis methods. A method for producing silver thiostannate by interaction of silver nitrate and tin(IV) sulfide is developed. It was found that in a medium with pH=3?4, Ag4Sn3S8 , compounds are obtained in molar ratios of AgNO3/SnS2=1:1, respectively. Depending on the concentration of components, temperature and thermal treatment time, particles of different sizes and shapes are obtained.
