Abstract
<jats:p>The article presents the results of obtaining thallium thioarsenate in ethylene glycol medium and physicochemical analysis methods (XRD, DTG, TG and SEM). It was found that when ethylene glycol is used as a solvent and TlNO3 and As2S5 as the initial component, thallium thioarsenate is obtained at 353 K temperature. Thallium thioarsenate is formed by the interaction of TlNO3 and As2S5 at a ratio of 4:15 mol. After the compound was obtained at a temperature of 353 K (pH = 7-8), thermally processed at a temperature of 523-543 K, the melting point of the thallium thioarsenate sample has been 683 K. According to the results of thermogravimetric analysis, at temperatures above 733 K thallium thioarsenate decomposes in nitrogen gas environment. The micromorphology of the Tl3AsS4 compound obtained in the ethylene glycol medium was studied and it was determined that nanoparticles of the Tl3AsS4 compound are formed at a temperature of 353 K.</jats:p>
