Biological role of Berylliumīeryllium is not the crucial element for human, in fact the element and its compounds are Toxic & Carcinogenic and it should be handled with the greatest care. The oxide has a very high melting point, so it is also used in nuclear work and ceramic applications. It is also used in Computer parts, and instruments where stiffness, lightness, and dimensional stability are required. Other uses are in brake discs, windshield frame, support beams, and other structural components of the space shuttle.īeryllium is relatively transparent to X-rays, so ultra-thin Beryllium-foil is finding use in X-ray lithography for the reproduction of micro-miniature integrated circuits.īe (Beryllium) is used in Nuclear reactors as a reflector or moderator of neutrons.
But on a fresh surface (without protective layer), beryllium dissolves readily in dilute acid such as Hydrochloric acid (HCl), Sulphuric acid (H 2SO 4), and Nitric acid (HNO 3), and forming Beryllium (II) ions and hydrogen gas (H 2).īa (s) + 2 H + (aq) → Ba 2+ (aq) + H 2 (g) Beryllium Historyĭiscovery: Nicolas Louis Vauquelin (1798) in Paris (France)įirst isolation: Friedrich Wöhler & Antoine Bussy (1828) Beryllium Usesīeryllium is used as an alloying agent in the production of beryllium-copper (BeCu, 1-3% Be) or beryllium-nickel (BeNi), which is extensively used to make Gyroscopes, Electrical contacts, Springs, Spot-welding Electrodes, and Non-sparking tools.īecause of Its electrical and thermal conductivity, high strength and hardness, good resistance, non-magnetic properties, It also used in the Defense and Aerospace industries as a structural material for high-speed aircraft, Missiles, Spacecraft, and Communication Satellites. The metal reacts with chlorine and bromine, and forming the corresponding Beryllium (II) dihalides.īe (s) + Br 2 (g) → BeBr 2 (s) Reaction with Acidsīeryllium is passivated by oxygen, and forming a beryllium oxide (BeO) which is resistant to acid. Normally beryllium cannot be oxidized, but powdered beryllium can be burn in air, and forming Beryllium Oxide (BeO), and Beryllium Nitride (Be 3N 2).ģ Be (s) + N 2 (g) → Be 3N 2 (s) Reaction with Waterīeryllium doesn’t react with water or steam, even if the metal is heated to red hot.
