What is Beryllium?

  • Beryllium is an element with an atomic number of 4 in the periodic table.
  • It is a bivalent and highly toxic element.
  • The element has one of the highest melting points among the light metals.
  • Beryllium exists in 30 different minerals, among which bertrandite, beryl, chrysoberyl, and phenacite are the most important.

Uses of Beryllium

  • Beryllium is used as an alloying agent.
  • It possesses high strength, non-magnetic properties, better resistance, and dimensionally stable over a significant range of temperature.
  • Beryllium fused with copper forms alloys which are used in defence and aerospace industries is a typical application of Beryllium.

Properties of Beryllium

  • It is non-magnetic, holds excellent thermal conductivity and resists attack by concentrated nitric acid.
  • Beryllium resists oxidation when exposed to air at standard temperature and pressure.
  • It is found in 30 different minerals of which bertrandite, phenakite, and Beryl are the most important.
  • Beryllium content in the ground can pass into the plants grown on it when it is in a soluble form.

Certain Facts About Beryllium
