SYNTHESIS OF PbSb2Se4 COMPOUND BY SOLVOTERMAL METHOD

In this research work the conditions of subsidence of nano- and microparticles of lead antimony selenide (PbSb2Se4) from the ethyleneglycol solutions are investigated. For formation of nanoparticles as a precursor of antimony we used salt antimony potassium tartrate, and for lead ? salt lead acetate (II). As selenide reagent, the sodium selenosulfate and solvent ethylene glycol were used. At the temperature of 443 K, after 15-hours syntheses there is the flocculated sludge. Chemical, thermographic, radiographic and morphological analyses of lead antimony selenide are carried out, and it is established that compound crystals are presented in the form of nano- and microwands.
