Stannic oxide Chemical Properties,Usage,Production
Description
Stannic oxide, also known as tin oxide, is an inorganic compound consisted of tin and oxygen, which is widely applied in various fields. The dominant usage of stannic oxide is to serve as a precursor in the production of other, especially trivalent, tin compounds or salts. It is also commonly employed as an opacifier in glazes. The addition of larger amounts of stannic oxide enhances the refractoriness of glazes and turns it from transparent to an opaque white. Stannic oxide is also used in the production of customized glass by giving transparent glass an opaque, porcelain-like, opaque appearance. It has proved to be a highly effective polishing material for glass and quarried rock, such as marble, granite and quartz. Besides, stannous oxide can be used for llumination with UV light in combination with cerium oxide in ceramic form. It also has a broad range of applications in other areas, such as semiconductors, photovoltaic materials, solar cells, lithium ion batteries, photocatalysts, and as gas-sensing agents in solid-state detectors.

Chemical Properties
white or off-white powder
Physical properties
White or grayish powder; tetragonal crystals; density 6.85 g/cm3; refractive index 2.006; Mohs hardness 6.5; melts at 1,630°C; insoluble in water; soluble in hot concentrated alkalies.
Uses
It is used to detect carbon monoxide. Used in ceramic glazes and colors, putty, perfume preparations, textiles, polishing powder for steel, and the manufacture of special glasses. Stannic oxide is also used in making white patinas.
Uses
Polishing glass and metals; manufacture of milk-colored, ruby and alabaster glass, enamels, pottery, putty; mordant in printing and dyeing fabrics; in fingernail polishes.
Uses
Stannic oxide (SnO2) is a whitish powder used as a ceramic glaze and polishing agent.
Definition
ChEBI: Tin dioxide is a tin oxide compound consisting of tin(IV) covalently bound to two oxygen atoms.
Preparation
Tin(II) oxide is prepared by heating tin(II) hydroxide. The latter is obtained as a white precipitate by reacting Sn2+ ions with hydroxide ions: Sn2+(aq) + 2OHˉ(aq) → Sn(OH)2 (s) Sn(OH)2 ?→ ?? SnO(s) + H2O(g).
General Description
White or off-white crystalline solid or powder. Mp 1127°C, Sublimes: 1800-1900°C, density: 6.95 g cm-3. Insoluble in water. Soluble in concentrated sulfuric acid, hydrochloric acid. Occurs in nature as the mineral cassiterite. Used as a catalyst, in putty, as a polishing powder for steel and glass, in ceramic glazes and colors. Flowers of tin refers to the material collected as the result of condensation after sublimation.
Reactivity Profile
TIN(IV) OXIDE is non-flammable and non-combustible. Reacts vigorously with strong reducing agents. Incompatible with chlorine trifluoride.
Battery Materials
In perovskite solar cells (PSCs), Stannic oxide (SnO2) is often employed as an electron transport layer (ETL) due to its excellent electron mobility and high transparency. Its function is to facilitate the efficient transport of photogenerated electrons from the perovskite layer to the external circuit, while also blocking holes, thereby improving the overall efficiency and stability of the solar cell. Using an aqueous solution of SnO2 can provide advantages such as ease of deposition, reduced toxicity, and environmental compatibility. This is particularly significant for scaling up the manufacturing process and aligns well with the sustainability goals often associated with renewable energy technologies like perovskite solar cells.
Purification Methods
Reflux it repeatedly with fresh HCl until the acid shows no tinge of yellow. The oxide is then dried at 110o.
Advantages
Stannic oxide, as the material of the electron transport layer, has good electronic conductivity and can effectively promote the rapid transmission of photogenerated electrons to the electrode.
