Tin(Sn) atomic and molecular weight, atomic number and elemental symbolTin is a Block P, Group 14, Period 5 element. Tin Bohr ModelThe number of electrons in each of Tin's shells is 2, 8, 18, 18, 4 and its electronic configuration is [Kr] 4d10 5s2 5p2. The tin atom has a radius of 140.5.pm and its Van der Waals radius is 217.pm. In its elemental form, CAS 7440-31-5, tin has a silvery or gray appearance. High Purity (99.9999%) Tin (Sn) MetalTin is commonly extracted from the mineral cassiterite, SnO2. The origin of the word tin comes from the Latin word Stannum which translates to the Anglo-Saxon word tin. Tin information, including technical data, safety data, high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on earth, conductivity and thermal properties are also included.

High Purity (99.999%) Tin Oxide (SnO) PowderTin salts and organometallic compounds of tin are very toxic, but tin in the form of single atoms or molecules is not toxic. Tin compounds sprayed onto glass are used to produce electrically conductive coatings. These have been used for panel lighting and for frost-free windshields. Most window glass is now made by floating molten glass on molten tin (float glass) to produce a flat surface. Crystalline tin-niobium alloy is superconductive at very low temperatures. This promises to be important in the construction of superconductive magnets that generate enormous field strengths but use practically no power. Tin is the basis for many eutectic alloys. The discovery by early man that copper could be better formed and crafted if tin were added produced the first bronze and launched what we refer to as the "Bronze Age". An important tin compound is the chloride, which is used as a reducing agent and as a mordant in calico printing. High Purity (99.9999%) Tin (Sn) Sputtering TargetTin is also used in various metal alloys (See AE Alloys). Tin is available in many specific states, forms and shapes including pellets, rod, wire and granules for evaporation source material purposes. Nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in forms including powders and dense pellets for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Tin is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries.

Safety data for tin metal, nanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific aluminum material or compound referenced in the “Tin Products” tab below.
