Bismuth Lead Cadmium Indium Alloy is one of numerous metal alloys sold by American Elements under the tradename AE Alloys™. Bismuth Lead Cadmium Indium Alloy is available as bar, ingot, ribbon, wire, shot, sheet, and foil. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, targets for thin film deposition, and pellets for evaporation. Bismuth Lead Cadmium Indium Alloy is generally immediately available in most volumes. Primary applications include bearing assembly, ballast, casting, step soldering, and radiation shielding. Bismuth is a Block P, Group 15, Period 6 element. The electronic configuration is [Xe] 4f14 5d10 6s2 6p3. In its elemental form bismuth's CAS number is 7440-69-9. The bismuth atom has a radius of 154.5.pm and it's Van der Waals radius is 200.pm. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall Effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field). Bismuth expands on solidification. This property makes bismuth alloys particularly suited to the making of sharp castings of objects subject to damage by high temperatures. With other metals such as tin, cadmium , etc., bismuth forms low-melting alloys which are extensively used for safety devices in fire detection and extinguishing systems. Bismuth is used in producing malleable irons and is finding use as a catalyst for making acrylic fibers. When bismuth is heated in air it burns with a blue flame, forming yellow fumes of the oxide. The metal is also used as a thermocoupling material, and has found application as a carrier for 235 U or 233 U fuel in nuclear reactors. Its soluble salts are characterized by forming unsoluble basic salts on the addition of water, a property sometimes used in detection work. Bismuth oxychloride is used extensively in cosmetics. Bismuth was first discovered by Early Man. Lead is a Block P, Group 14, Period 6 element. The electronic configuration is [Xe] 4f14 5d10 6s2 6p2. In its elemental form lead's CAS number is 7439-92-1. The lead atom has a radius of 175.pm and it's Van der Waals radius is 202.pm. Lead is a bluish-white metal of bright luster, naturally occurring as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%). It is highly resistant to corrosion and can be used to contain corrosive liquids such as sulfuric acid. Great quantities of Lead, both as the dioxide and the metal, are used in batteries, cable covering, plumbing, and ammunition. Alloys include solder, type metal, and various antifriction metals and compounds. Lead is extremely effective at absorbing sound and vibration. It is also used as radiation shielding for X-ray equipment and nuclear reactors. Oxides of Lead are used in producing fine "crystal glass" and "flint glass" of a high index of refraction for achromatic lenses. Lead ceramics and crystalline material have a wide range of industrial and optical applications, including infrared detection and imaging. Lead-based semiconductors, such as lead telluride, lead selenide and lead antimonide are finding application in photovoltaic (solar energy) cells and infra red detectors. Cadmium is a Block D, Group 12, Period 5 element. The electronic configuration is [Kr] 4d10 5s2. In its elemental form cadmium's CAS number is 7440-43-9. The cadmium atom has a radius of 148.9.pm and it's Van der Waals radius is 158.pm. Cadmium is a component of some of the lowest melting alloys; it is used in bearing alloys with low coefficients of friction and great resistance to fatigue. Cadmium is used extensively in electroplating, which accounts for about 60% of its use. It is also used in many types of solder, for standard E.M.F. cells, for nickel-cadmium batteries, and as a barrier to control nuclear fission. Cadmium compounds are used in black and white television phosphors and in blue and green phosphors for color television tubes and CRT monitors. Cadmium in glass and ceramic glazes creates a distinctive cadmium yellow. It forms a number of compounds, of which the sulfate is most common; the sulfide is used as a yellow pigment. Cadmium is similar to carbon in that it has a capacity to form stable covalently bonded molecular networks. Cadmium was first discovered by Fredrich Stromeyer in 1817. Indium is a Block P, Group 13, Period 5 element. The electronic configuration is [Kr] 4d10 5s2 5p1. In its elemental form indium's CAS number is 7440-74-6. The indium atom has a radius of 162.6.pm and it's Van der Waals radius is 193.pm. Indium has found application in semi-conductor materials and other electronic applications. It is used to make low-melting alloys, such as an alloy of 24% indium - 76% Indium is liquid at room temperature. It is used in making bearing alloys, germanium transistors, rectifiers, and photoconductors. It can be plated onto metal and evaporated onto glass, forming a mirror as good as that made with silver but with more resistance to atmospheric corrosion. Indium 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. Indium is also used in various metal alloys (See AE Alloys).
