What are facts about beryllium?

Answer 1

Beryllium is an alkaline-earth metal, atomic number 4, Atomic Mass 9,01282(3); very toxic, it is the cause of berylliosis.

Applications:

- alloying metal for copper alloys (alloys for welding electrodes, components in electrotechnics, springs for watches - from glycodur)

- rockets, missiles, aviation

- brazing material for zirconium and zirconium alloys

- reflector in nuclear reactors (as metal or oxide)

- windows for X-ray tubes or X-ray detectors

- component of neutron sources (Ra-Be, Pu-Be, Am-Be, Po-Be, etc.)

- components for large particles accelerators

- mirrors for astronomy, military armored vehicles, etc.

- special components for electronics

- beryllium oxide: ceramic material for burning boats, tubes of reaction, crucibles, tubes for thermocouples, thermal isolator in electronics, etc.

- BeF2 was used in the experimental reactor MSRE

- beryllium nitride (Be3N2) is a refractory ceramics and the the source material to prepare the isotope 14C

- and other applications

1. The colour of Beryllium is a steel grey

2. The structure of Beryllium is HCP (hexagonal close packed)

3. Beryllium and its salts are both toxic and carcinogenic

4. It has high thermal conductivity and is nonmagnetic

Answer 2

Atomic Number 4, Atomic Symbol Be, Melting Point 1560 K, Boiling Point 2742 K, Appearance = White-Grey Metallic, Discovered By Louis-Nicolas Vauquelin in 1798, Friedrich Wöhler and Antoine Bussy independently isolated the metal in 1828, Crystal Structure=Hexagonal, Density 1.85 grams per cubic centimetre, Element Catagory=Alkaline earth metal. Bonus fact, thin sheets of beryllium foil are used as windows in X-ray detectors to filter out visible light and allow only X-rays to be detected.

and. Be has a very high velocity for sound waves, almost 13km/sec.
