Abstract
The possibilities of crystal growth of ultimate sulfides in molten sulfur in a stationary temperature gradient are described. The optimum synthesis mode is achieved when the temperature of the hot end (charge) is 550°C, the temperature of the cold end (crystallization) is 460°C. As a result, crystals of TiS3, ZrS3, HfS3, V40S60, NbS3, TaS3, PdS2, CuS, Ag2S, metallic Au, HgS, CdS, Ga2S3, In2S3, SiS2, SnS2, PbS, Sb2S3 and Bi2S3 of millimeter and submillimeter size were obtained. Only polycrystalline agglomerates of tens of microns in size were obtained when transferring some metals, such as tungsten. The possibility of obtaining crystals of double sulfides is shown using CrPS3 as an example. The considered technique allows obtaining crystals of the required quality without using special equipment. The small size of the crystals is sufficient for laboratory study.
