About Beryllium Borohydride

Hydride IonBeryllium Borohydride is generally immediately available in most volumes. Beryllium Borohydride has an extremely high total hydrogen storage capacity. Originally, Be(BH4)2 was prepared by reaction of BeMe2 with diborane and, more expediently, by mechanochemical exchange response of BeCl2 with alkali metal borohydrides followed by vacuum distillation at 140 °C. This covalent compound is built of helical polymeric chains -BeH2BH2BeH2BH2- and terminal bidentate BH4 groups. Beryllium Borohydride is very unstable, exploding on contact with air and moisture. Unfortunately, the intense toxicity of beryllium, and very high reactivity of Be(BH4)2, makes this material inappropriate for hydrogen storage despite low decomposition temperature and high frequency. American Elements offers a broad range of products for hydrogen storage research, advanced fuel cells and battery applications. Hydrogen can easily be generated from renewable energy sources and is the most abundant element in the universe. Hydrogen is produced from various sources such as fossil fuels, water and renewables. Hydrogen is nonpolluting and forms water as a harmless byproduct during use. The challenges associated with the use of hydrogen as a form of energy include developing safe, compact, reliable, and cost-effective hydrogen storage and delivery technologies. Currently, hydrogen can be stored in these three forms: Compressed Hydrogen, Liquid Hydrogen and Chemical Storage. High purity, submicron and nanopowder forms may be considered. Hydride compounds are used often used as portable sources of hydrogen gas. 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.

Beryllium Bohr ModelThe number of electrons in each of Beryllium's shells is [2, 2] and its electron configuration is [He] 2s2. The beryllium atom has a radius of 112 pm and a Van der Waals radius of 153 pm. Beryllium is a relatively rare element in the earth's crust; it can be found in minerals such as bertrandite, chrysoberyl, phenakite, and beryl, its most common source for commercial production. Beryllium was discovered by Louis Nicolas Vauquelin in 1797 and first isolated by Friedrich Wöhler and Antoine Bussy in 1828. Elemental BerylliumIn its elemental form, beryllium has a gray metallic appearance. It is a soft metal that is both strong and brittle; its low density and high thermal conductivity make it useful for aerospace and military applications. It is also frequently used in X-ray equipment and particle physics. The origin of the name Beryllium comes from the Greek word "beryllos," meaning beryl.

The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s2 2p1. The boron atom has a radius of 90 pm and a Van der Waals radius of 192 pm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808 and was first isolated by Humphry Davy later that year. Boron is classified as a metalloid is not found naturally on earth. Elemental BoronAlong with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds featuring triple bonds. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. The name Boron originates from a combination of carbon and the Arabic word buraqu meaning borax.
