Stannic Sulfide Properties

About Stannic Sulfide SnS2 Powder:
Tin disulfide, or stannic sulfide is an inorganic compound. Stannic sulfide formula is SnS2. It is a yellow hexagonal flake with a CdI2 crystal structure. It is hardly soluble in water, but it is soluble in aqua regia and hot alkali solution, and also soluble in sodium sulfide solution. Stannic sulphide is commonly used to make golden paint.
Tin(IV) sulfide crystallizes in the form of cadmium iodide precursor crystals, where Sn(IV) is located in an "octahedral pore" defined by six sulfide centers. It naturally appears as rare mineral montmorillonite, which can be used as a semiconductor material with a bandgap of 2.2 eV.
SnS2 is an n-type semiconductor material with a hexagonal CdI2 structure. Tin disulfide SnS2 is a layered metal dihalide semiconductor with a chemical and crystal structure similar to molybdenum disulfide (MoS2). In each individual layer, Sn is sandwiched between two Slayers with strong covalent bonds, while a single monolayer is maintained by weak van der Waals forces. When the weak van der Waals force is overcome by physical or chemical peeling, each layer will break freely.
Like many other two-dimensional semiconductors, SnS2 exfoliates to form atomic layer sheets, which can be used in FET, photovoltaic solar cells, sensors, and photocatalyst applications.
Tin disulfide is an acidic sulfide, soluble in aqua regia and hot alkali solution, and can undergo coordination reaction with concentrated hydrochloric acid, but it is insoluble in dilute hydrochloric acid, insoluble in water and nitric acid. It can react with ammonium sulfide to dissolve.

How is Stannic Sulfide SnS2 Powder produced?
A bright yellow tin disulfide precipitate can be obtained by passing hydrogen sulfide into the acid solution of tin tetrachloride
In addition, selenium disulfide can also be prepared by the action of sulfide on tin chloride solution.
Tin disulfide can be obtained by directly combining tin and sulfur in the presence of iodine. The reaction requires heating:
Sn + 2 S → SnS2
Another method is to pass hydrogen sulfide into the tin (IV) salt or tin (IV) salt solution and precipitate it.


Applications of Stannic Sulfide SnS2 Powder:
Tin disulfide (SnS2) is a two-dimensional van der Waals semiconductor material with excellent photoelectric properties. The material is non-toxic, environmentally friendly, rich in content and easy to prepare. The properties of tin sulfide are semiconductors, which are mainly used in laboratory research and development and experiments, and are currently very active in the market.
Tin disulfide is an n-type semiconductor material with a layered hexagonal CdI2 crystal structure and a wide bandgap of about 2.35 eV; the wide bandgap makes it have good optical and electrical properties and can be used for holographic recording and electrical conversion System materials, solar cell materials and anode materials of Lithium Chemicalbook sub-cells, etc.
Because tin disulfide has a bandgap similar to silicon, is safe and environmentally friendly, and has a high absorption coefficient, it is very suitable as an absorber layer for solar cells. In recent years, it has become a research hotspot for domestic and foreign experts. It can also be used for imitation gold plating and manufacturing. Used for paints and so on.
Tin disulfide single crystals can be used to prepare single-layer and few-layer SnS2 by mechanical or liquid stripping.
Tin disulfide powder is suitable for liquid chemical exfoliation to prepare SnS2 nanosheets and nanoparticles as low as a few layers of thin films.
Tin disulfide has high sensitivity and high surface activity. The exfoliated SnS2 single-layer or multi-layer ultra-thin film made of bulk crystals and powder has also been used in light emitters, field-effect transistors (FET), gas sensors, and photodetectors. , Thermoelectric photovoltaic and other fields and energy storage equipment, such as the application of lithium-ion batteries.

FAQs of Stannic Sulfide SnS₂ Powder:

Q: What is stannic sulfide used for?

A: Stannic sulfide (SnS₂) powders are employed in a variety of applications due to their unique properties. They are commonly used as pigments in paints and coatings, providing a golden-yellow color with good lightfastness and heat stability. In the field of electronics, SnS₂ is explored for its semiconducting properties, making it suitable for use in photodetectors, solar cells, and other optoelectronic devices. The material's layered structure allows for interesting electronic and optical behaviors that can be exploited in these technologies. Additionally, stannic sulfide finds application in catalysis, serving as a catalyst or catalyst support in various chemical reactions. Its ability to withstand high temperatures also makes it valuable in refractory materials and ceramics.
 

Q: Is stannic sulfide safe for human exposure?

A: Exposure to stannic sulfide should be managed carefully. While there is limited specific data on the health effects of SnS₂, fine particles of this compound may cause irritation to the respiratory system, eyes, and skin. Proper handling practices include using personal protective equipment (PPE) such as gloves, safety goggles, and appropriate respiratory protection when dealing with airborne dust. Adequate ventilation and adherence to occupational exposure guidelines are important to minimize potential risks. Always refer to the Safety Data Sheet (SDS) provided by the supplier for detailed information on potential health impacts and safe handling procedures.
 

Q: What is the formula and structure of stannic sulfide?

A: Stannic sulfide has the chemical formula SnS₂, indicating it consists of one tin atom (Sn) and two sulfur atoms (S). This compound crystallizes in a layered structure known as the mica-type structure, characterized by sheets of tin and sulfur atoms stacked on top of each other. Each layer is composed of corner-sharing SnS₄ tetrahedra, which gives rise to strong covalent bonds within the layers and weaker van der Waals forces between them. This arrangement results in a material that exhibits anisotropic properties, meaning its physical characteristics can differ depending on the direction in which they are measured. The layered structure contributes to SnS₂'s semiconducting behavior and makes it an interesting material for research into new electronic and optical devices.
 

Q: Can stannic sulfide be incorporated into composite materials?

A: Yes, stannic sulfide can be integrated into composite materials to enhance certain properties such as electrical conductivity, thermal stability, and catalytic activity. Composites containing SnS₂ benefit from its inherent qualities while offering improved design flexibility and functionality. For instance, incorporating SnS₂ into polymer matrix composites can yield materials with tailored electronic properties suitable for use in sensors or photonic devices. When used as a filler in ceramics or glasses, SnS₂ can improve thermal stability and mechanical strength. Moreover, SnS₂ nanoparticles can be dispersed within metal matrices to create nanocomposites with enhanced wear resistance and lubricating properties. The versatility of SnS₂ makes it a valuable component in developing innovative materials across multiple industries, including electronics, optics, and energy storage.
