Let's Learn About BERYLLIUM!


Beryllium is a silvery-white metal. It is relatively soft and has a low density.
Named after beryllos, the Greek name for the mineral beryl, the element was originally known as glucinium — from Greek glykys, meaning “sweet” — to reflect its characteristic taste. But the chemists who discovered this unique property of beryllium also found that it is in fact highly toxic and should therefore never be tasted,
It is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.

Beryllium is used in gears and cogs particularly in the aviation industry.  Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites. It is relatively transparent to X-rays so ultra-thin beryllium foil is finding use in X-ray lithography. It is also used in nuclear reactors as a reflector or moderator of neutrons.

The oxide has a very high melting point making it useful in nuclear work as well as having ceramic applications.

Beryllium and its compounds are toxic and carcinogenic. If beryllium dust or fumes are inhaled, it can lead to an incurable inflammation of the lungs called berylliosis.
