Lead Tungstate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.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.
Lead is a Block P, Group 14, Period 6 element. The number of electrons in each of Lead's shells is 2, 8, 18, 32, 18, 4 and its 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 and its compounds are poisonous. 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. Lead was first discovered by Early Man. The origin of the name Lithium comes from the Greek word protos meaning "first". See Lead research below.
Tungsten is a Block D, Group 6, Period 6 element. The number of electrons in each of Tungsten's shells is 2, 8, 18, 32, 12, 2 and its electronic configuration is [Xe] 4f14 5d4 6s2. In its elemental form tungsten's CAS number is 7440-33-7. The tungsten atom has a radius of 137.pm and it's Van der Waals radius is 200.pm. Tungsten is considered to be only mildly toxic. Tungsten has the highest melting point of all the metallic elements and because of this has its first significant commercial application as the filament in incandescent light bulbs and fluorescent light bulbs. Tungsten is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Later it was used in the first television tubes. The first imaging equipment involved X-ray bombardment of a tungsten target. Tungsten expands at nearly the same rate as borosilicate glass and is used to make metal to glass seals. It is the primary metal in heating elements for electric furnaces and in any components where high pressure/temperature environments are expected, such as aerospace and engine systems. Tungsten was first discovered by Fausto and Juan Jose de Elhuyar in 1783. In reference to its density, Tungsten gets its name from the swedish words tung and sten meaning heavy stone. See Tungsten research below.
