Stannic Sulfide powder: Properties
Stannic Sulfide has a low solubility in water. It is, however, soluble when mixed with aqua regia or hot alkaline. Stannic Sulfide is used in golden paints.
Stannic Sulfide dissolves in aqua regia or hot alkali solution and undergoes a coordination reaction with concentrated Hydrochloric Acid. However, it is insoluble when dilute and insoluble when water and nitric acids are used. Stannic Sulfide can be dissolved by ammonium sulfide.
Stannic Sulfide Application
Stannic Sulfide (SnS2), a van-der-Waals semiconductor material in two dimensions with excellent photoelectric characteristics, is one of the semiconductors with the fastest response time to photoelectric signals reported. It is also non-toxic and environmentally friendly.
The researchers used a traditional chemical vapor transfer method to determine the best growth conditions in order to obtain high quality Fe-SnS2 crystals. After that, they obtained two-dimensional FeSnS2 sheets by mechanical lifting-off. Scanning transmission-electron microscopy (STEM), results show that Fe is doped in the place of Sn and is evenly distributed.
Theoretical calculation shows that Fe-SnS2 magnetism comes from antiferromagnetic interactions between Fe and adjacent S, while the adjacent Fe atoms have ferromagnetic interactions. This results in long-range magnetic iron being formed by this magnetic atom doped material. Research shows that iron-doped, stannic sulfide may have applications in the future for nanoelectronics as well magnetism and optical electronics.
