Zinc Germanium Phosphorus Lump is a semiconductor used in high power, high frequency applications and in laser diodes.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Zinc is a Block D, Group 12, Period 4 element. The number of electrons in each of Zinc's shells is 2, 8, 18, 2, and its electronic configuration is [Ar] 3d10 4s2. In its elemental form zinc's CAS number is 7440-66-6. The zinc atom has a radius of 133.5.pm and it's Van der Waals radius is 139.pm. Combined with other elements as ores, Zinc is found in nature. Zinc is considered non-toxicin healthy doses but can cause nausea if taken in excess. Zinc is a bluish-white, lustrous metal which we produce in Special High Grade (SHG) purities. It is brittle at ordinary temperatures but malleable at 100 to 150 o C. It is a fair conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. It has unusual electrical, thermal, optical, and solid-state properties that have not been fully investigated. The metal is employed to form numerous alloys with other metals. Brass, nickel, silver, commercial bronze, soft solder, and aluminum solder are some of the more important alloys. Large quantities of zinc are used to produce die castings, which are used extensively by the automotive, electrical, and hardware industries. Zinc is also used extensively togalvanize other metals such as iron to prevent corrosion. Zinc oxide is widely used in the manufacture of paints, rubber products, cosmetics, pharmaceuticals, floor coverings, plastics, printing inks, soap, storage batteries, textiles, electrical equipment, and other products. Zinc sulfide is used in making luminous dials, X-ray and TV screens, and fluorescent lights The chloride and chromate are also important compounds. Zinc 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. Zinc was first discovered by Andreas Marggraf in 1746. The element name Zinc originates from the German word "zin" meaning tin. See Zinc research below. See Zinc research below.
Germanium is a Block P, Group 14, Period 4 element. The number of electrons in each of Germanium's shells is 2, 8, 18, 4 and its electronic configuration is [Ar] 3d10 4s2 4p2. In its elemental form germanium's CAS number is 7440-56-4. The germanium atom has a radius of 122.5.pm and it's Van der Waals radius is 200.pm. Germanium is not toxic. Germanium is a very important semiconductor. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with extremely high purities. When germanium is doped with arsenic, gallium, or other elements, it is used as a transistor element in thousands of electronic applications. The most common use of germanium is as a semiconductor. Germanium is also finding many other applications including use as an alloying agent, as a phosphor in fluorescent lamps, and as a catalyst. Germanium and germanium oxide are transparent to the infrared and are used in infrared spectroscopes and other optical equipment, including extremely sensitive infrared detectors. The high refractive index and dispersion properties of its oxide's have made germanium useful as a component of wide-angle camera lenses and microscope objectives. The field of organo-germanium chemistry is becoming increasingly important. Germanium was first discovered by Clemens Winkler in 1886. See Germanium research below.
Phosphorus is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s2 3p3. In its elemental form Phosphorus's CAS number is 7723-14-0. The Phosphorus atom has a radius of 110.5.pm and it's Van der Waals radius is 180.pm. Although white phosphorus is very toxic, red phosphorus is not considered toxic. Phosphorus information, including Technical Data, Safety Data and its 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 included.
