Zamkovi skhody 4b, 88000, Uzhgorod, Ukraine aut Preparation and some properties of high-purity PbGa2Se4 [Elektronische Daten] [M. Rigan] Polycrystalline PbGa2Se4 was synthesized from commercially available and additionally purified Pb, Ga, and Se. As shown by chemical analysis, the material prepared from as-purchased reagents exhibited significant deviations from stoichiometry. According to microstructural analysis, this material contained a second phase. PbGa2Se4 synthesized from additionally purified Pb, Ga, and Se was uniform in composition. The highest degree of purification was ensured by the Bridgman-Stockbarger method, which enabled growth of stoichiometric single crystals. Attempts to purify PbGa2Se4 by directional solidification, zone melting, and thermal evaporation led to decomposition of the material. According to mass spectrometry results, the major products of PbGa2Se4 decomposition are PbGa2 , Ga2Se, Pb, and Se2.
