Using potassium antimoniltartratе in ethylene glycol and sulfur in ethylendiamine (as sulphidizing reagent) the nanocrystals of antimony trisulfide have been obtained. Absorption spectra were taken, the termographic, X-ray phase analyses were made and it was established that antimony trisulfide represents nanocrystals of rod form. The conditions of growth of nanorods of  Sb₂S₃ compounds crystals at different temperatures have been studied.
