BST (Barium Strontium Titanate) 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.
Barium is a Block S, Group 2, Period 6 element. The number of electrons in each of Barium's shells is 2, 8, 18, 18, 8, 2 and its electronic configuration is [Xe] 6s2. In its elemental form barium's CAS number is 7440-39-3. The barium atom has a radius of 217.4.pm and it's Van der Waals radius is 200.pm. Barium powder can ignite spontaneously in air and when Barium compounds are water or acid soluble, they are very poisonous. Barium sulfate which is used in x-ray imaging, is highly insoluble in water, and consequently completely removed from the digestive tract. Barium is a member of the alkaline-earth metals. Barium is more reactive than calcium although they are chemically similar. It has technical applications in glass, electronics and medicine. It is also used in paints and colorants. Electronic coatings based on barium titanate are essential to cell phones and other microelectronics. It has long been used in medical diagnostic techniques because it makes a good x-ray contrast medium. Barium is a dopant in various fluorescent lamp coating formulas. Barium information, including Technical Data, Safety Data and its High Purity properties , research , applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy , abundance on Earth , conductivity and thermal properties are included.
Strontium is a Block S, Group 2, Period 5 element. The number of electrons in each of Strontium's shells is 2, 8, 18, 8, 2 and its electronic configuration is [Kr] 5s2. In its elemental form strontium's CAS number is 7440-24-6. The strontium atom has a radius of 215.1.pm and it's Van der Waals radius is 200.pm. The non-radioactive isotopes of Strontium are not toxic. Strontium has low tech applications as an additive to flares and pyrotechnics because of the bright crimson flame produced by its salts. Strontium 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. It also has many high technology applications because of its high refractive index as a titanate in glass, as a "getter" in electron tubes and as a dopant for numerous perovskite formulations to produce cathodes for oxygen generation or solid oxide fuel cells. Historically the primary use of strontium was to produce CRT glass for color television and computer tubes. Strontium was first discovered by A. Crawford in 1790. Strontium was named after the Scottish town it was discovered in, Strontian. See Strontium research below.
