A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. butyltin trichloride as the volatile agent. [11], This oxide of tin has been utilized as a mordant in the dyeing process since ancient Egypt. Such materials appear to be hydrated particles of SnO2 where the composition reflects the particle size. with CuO[25]). This technique is used to coat glass bottles with a thin (<0.1 μm) layer of SnO2, which helps to adhere a subsequent, protective polymer coating such as polyethylene to the glass. Occurs in nature as the mineral cassiterite. It also has oxide ions in it. Joseph Watson The stannic oxide semiconductor gas sensor in The Electrical engineering Handbook 3d Edition; Sensors Nanoscience Biomedical Engineering and Instruments ed R.C Dorf CRC Press Taylor and Francis. One report describes reacting a sample in refluxing HI for many hours.

[19], SnO2 has been used as pigment in the manufacture of glasses, enamels and ceramic glazes. 2SnO + O 2 2SnO 2 [ Check the balance ] ... 2 SnO + O2 cnd [ temp ] = 2 SnO2. Tin (IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO 2. Scott, Greenwood & son. It is a colourless, diamagnetic, amphoteric solid. | CH2NH ’Ceramic Glazes’ Third edition.

Soluble in concentrated sulfuric acid, hydrochloric acid. It is normally a blue-black solid. Doping with cobalt and manganese, gives a material that can be used in e.g. The purity, surface chemical composition, and electronic structure up to a depth of about 22 nm (photon energy = 650.0 eV) of SnO 2 thin film were determined by XPS. London. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. Melting point 340 deg C. Density 3.954 g / cm3. "Flowers of tin" refers to the material collected as the result of condensation after sublimation. The as-prepared SnO2 nanosheets contained plenty of nano-voids and were generally vertical to the substrate. [16] This has probably led to the discovery of the pigment lead-tin-yellow, which was produced using tin(IV) oxide as a compound. It dissolves in acids to make a colorless solution. high voltage varistors. It is rarer than tin(IV) oxide. The near-surface chemical composition of the sample was analyzed by XPS measurement within a range of binding energies of −10.0 to 610.0 eV. Synthesis, characterization and ethanol vapor sensing performance of SnO2/Graphene composite film. [11] Dissolving the solidified SnO2/NaOH melt in water gives Na2[Sn(OH)6]2, "preparing salt," which is used in the dye industry. There will be a fixed ratio for a chemical compound determining the composition of it. [11] Annual production is in the range of 10 kilotons. [17] The use of tin(IV) oxide has been particularly common in glazes for earthenware, sanitaryware and wall tiles; see the articles tin-glazing and Tin-glazed pottery. [9], Thicker layers doped with Sb or F ions are electrically conducting and used in electroluminescent devices and photovoltaics. [15], Similarly, SnO2 dissolves in sulfuric acid to give the sulfate:[11], SnO2 dissolves in strong bases to give "stannates," with the nominal formula Na2SnO3. Special ChemDoodle Offer. Tin dioxide (stannic oxide) is the inorganic compound with the formula SnO2. P.G. EPA Registry Name: Tin dioxide. [9] With many other names, this oxide of tin is an important material in tin chemistry. The lung can be exposed to a variety of reactive nitrogen intermediates through the inhalation of environmental oxidants and those produced during inflammation. With many other names (see infobox), this oxide of tin is the most important raw material in tin chemistry. Tin oxide remains in suspension in vitreous matrix of the fired glazes, and, with its high refractive index being sufficiently different from the matrix, light is scattered, and hence increases the opacity of the glaze. The degree of dissolution increases with the firing temperature, and hence the extent of opacity diminishes. ", Tin oxides dissolve in acids. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The physical characteristics of the films as a function of both water content in the starting solution and substrate temperature were studied. [11], In conjunction with vanadium oxide, it is used as a catalyst for the oxidation of aromatic compounds in the synthesis of carboxylic acids and acid anhydrides. Systematic Name: Tin oxide (SnO2) IUPAC Name: Stannanedione CAS Number: 18282-10-5. [11], Tin(IV) oxide occurs naturally. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide The corner-sharing octahedral tilt angles are 51°. Halogen acids attack SnO2 to give hexahalostannates,[14] such as [SnI6]2−. It is used to make a glass with gold in it called ruby glass. Room temperature gas sensors are also being developed using reduced graphene oxide-SnO2 composites(e.g. Tin(II) oxide, also known as stannous oxide, is a chemical compound.
