Silver-Tin Alloy Nanopowder

Ag_0.035Sn_0.965 Nanoparticles

Silver-tin Alloy ( Ag_0.035Sn_0.965) Nanopowder or Nanoparticles are typically < 150 nanometers (nm) with a BET surface area of > 5.4 m2/g. Nano Silver-tin Alloy Particles are also available in ultra high purity and high purity, transparent, and coated and dispersed forms. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil.

Silver-tin Alloy Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Silver is a Block D, Group 11, Period 5 element. The electronic configuration is [Kr]4d¹⁰5s¹. In its elemental form silver's CAS number is 7440-22-4. The silver atom has a radius of 144.5.pm and it's Van der Waals radius is 144.pm. Silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. Silver nitrate has wide application in painting, xerography, chemical electroplating, in components for electric batteries and in medicine as catalyst. Silver chloride is another important compound, due to its ductility and malleability. The organic compounds of the element are used in the coating of several metals and in dynamite or other explosive bars. Metallic silver is used as a catalyst of several oxidation reactions such as those of ethanol and other alcohols. Silver is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.  Silver is also used in various metal alloys (See AE Alloys).

Tin is a Block P, Group 14, Period 5 element. The electronic configuration is [Kr] 4d¹⁰ 5s² 5p². In its elemental form tin's CAS number is 7440-31-5. The tin atom has a radius of 140.5.pm and it's Van der Waals radius is 217.pm. 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 and the discovery by early man that copper could be better formed and crafted if tin were added producing the first bronze and launching what we refer to as the "Bronze Age" and the first Neolithic metal tools, cooking utensils, and jewelry produced from rudimentary bronze. An important tin compound is the chloride, which is used as a reducing agent and as a mordant in calico printing.  Tin is also used in various metal alloys (See AE Alloys). Tin was first discovered by Early Man.
