Beryllium metal has the unique physical and mechanical properties that cannot be found in the other metals. Its high permeability of X-ray is applied for X-ray generator's apparatus, its high-speed sound transmission for diaphragms in speakers, its lightweight and strength in the aviation and the space field, and its nuclear special property in the nuclear energy industry.

Beryllium was discovered by Louis-Nicolas Vauquelin (Fr) in 1798 as the oxide in beryl and in emeralds. The name beryllium comes from the Greek ‘’bērullos’’, in reference to the pale semiprecious gemstone beryl. At one time beryllium was referred to as ‘glucinium’, the name coming from the Greek word ‘’glykis’’ for sweet, due to the sweet taste of its salts.


Beryllium is a mineral extracted from the ground mainly in an oxide state. A bivalent element, beryllium is a steel grey metal that can be mostly found in the minerals, the most important of which are bertrandite [AlBe3(Si6O18)], chrysobéryl (Al2BeO4), and phenakite (Be2SIO4).

Precious forms of beryl are aquamarine, bixbite and emerald. Pure beryllium is obtained by reduction of beryl or by electrolyse of the beryllium chloride. At this state, pure beryllium metal has a high thermal conductibility and is non-magnetic.
