(Gr. beryllos, beryl; also called Glucinium or Glucinum, Gr. glykys, sweet) Discovered as the oxide by
Vauquelin in beryl and in emeralds in 1798. The metal was isolated in 1828 by Wohler and by Bussy
independently by the action of potassium on beryllium chloride.
Sources
Beryllium is found in some 30 mineral species, the most important of which are bertrandite, beryl,
chrysoberyl, and phenacite. Aquamarine and emerald are precious forms of beryl. Beryl and bertrandite
are the most important commercial sources of the element and its compounds. Most of the metal is now
prepared by reducing beryllium fluoride with magnesium metal. Beryllium metal did not become readily
available to industry until 1957.
Properties
The metal, steel gray in color, has many desirable properties. As one of the lightest of all metals, it has
one of the highest melting points of the light metals. Its modulus of elasticity is about one third greater
than that of steel. It resists attack by concentrated nitric acid, has excellent thermal conductivity, and is
nonmagnetic. It has a high permeability to X-rays and when bombarded by alpha particles, as from
radium or polonium, neutrons are produced in the amount of about 30 neutrons/million alpha particles.
At ordinary temperatures, beryllium resists oxidation in air, although its ability to scratch glass is
probably due to the formation of a thin layer of the oxide.

Beryllium
Uses
Beryllium is used as an alloying agent in producing beryllium copper, which is extensively used for
springs, electrical contacts, spot-welding electrodes, and non-sparking tools. It is applied as a structural
material for high-speed aircraft, missiles, spacecraft, and communication satellites. Other uses include
windshield frame, brake discs, support beams, and other structural components of the space shuttle.
Because beryllium is relatively transparent to X-rays, ultra-thin Be-foil is finding use in X-ray
lithography for reproduction of micro-miniature integrated circuits.
Beryllium is used in nuclear reactors as a reflector or moderator for it has a low thermal neutron
absorption cross section.
It is used in gyroscopes, computer parts, and instruments where lightness, stiffness, and dimensional
stability are required. The oxide has a very high melting point and is also used in nuclear work and
ceramic applications.
