Barium Chromate 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.

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. 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. See Barium research below.
Chromium is a Block D, Group 6, Period 4 element. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electronic configuration is [Ar] 3d5 4s1. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Hexavalent chromium is toxic. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green. Chromium 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 is also used as a paint pigment for this purpose.Although chromium metal is an essential trace element, hexavalent chromium (Cr(VI)) is especially toxic and carcinogenic. Recently, chromites have formed the basis for cathode compositions for oxygen generation and fuel cell applications. Chromium 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. Chromium was first discovered by Anders Ekeberg in 1802. Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color. See Chromium research below.
