Description
Tin sulfide is an n-type semiconductor material with a layered hexagonal CdI2 crystal structure and a wide band gap of about 2.35eV; the wider band gap 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 for lithium electronic batteries, etc.
Chemical Properties
Yellow to brown powder. Soluble in concentrated hydrochloric acid and alkaline sulfides; insoluble in
water. Flaky or scaly crystals with a high gold-yellow sheen, soft as
talc; very stable in air. On heating, the color deepens reversibly
to dark red, then to deep brown, above about 600°C decomposition
to SnS and S takes place.
Uses
Gilding and bronzing metals, gypsum, wood and paper, usually by suspending in lacquer or varnish.
Uses
Tin sulfide is a 2D van der Waals semiconductor material with excellent optoelectronic properties. The material is non-toxic, environmentally friendly, rich in content and easy to prepare. It is mainly used for laboratory research and development and experiments.
Definition
ChEBI: Tin disulfide is a sulfide salt.
Hazard
Irritant to skin and eyes
Flammability and Explosibility
Not classified
Synthesis
Tin sulfide can be prepared as a bright yellow precipitate by the action of hydrogen sulfide on tin chloride solution.
Tin sulfide can also be prepared by the reaction of the metal element tin with monomeric sulphur.
Sn + 2 S = SnS2
