Abstract <p>The possibilities of growing ultimate sulfide crystals from a sulfuric melt in a stationary temperature gradient are described. The optimum synthesis mode is achieved when the temperature of the hot end (charge) is 550°C and the temperature of the cold end (crystallization region) is 460°C. As a result, TiS₃, ZrS₃, HfS₃, V₄₀S₆₀, NbS₃, TaS₃, PdS₂, CuS, Ag₂S, metallic Au, HgS, CdS, Ga₂S₃, In₂S₃, SiS₂, SnS₂, PbS, Sb₂S₃, and Bi₂S₃ crystals of millimeter and submillimeter sizes were grown. Only polycrystalline agglomerates several tens of micrometers in size were obtained when transferring some metals, in particular, tungsten. The possibility of growing crystals of double sulfides was demonstrated using CrPS₃ as an example. The considered technique makes it possible to obtain crystals of the required quality without special equipment; the small size of crystals is sufficient for laboratory study.</p>
