Beryllium has no known biological role, and its dust causes chronic inflammation of the lungs and shortage of breath. Brief exposure to a lot of beryllium, or long exposure to a little, will bring on this lung condition which is known as berylliosis.
Preparation and chemical properties. Beryllium oxide can be prepared by calcining (roasting) beryllium carbonate, dehydrating beryllium hydroxide, or igniting metallic beryllium: BeCO 3 → BeO + CO 2 Be(OH) 2 → BeO + H 2 O 2 Be + O 2 → 2 BeO. Igniting beryllium in air gives a mixture of BeO and the nitride Be 3 N 2.

Beryllium is a silvery white metal. The surface of beryllium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. It does not oxidize in air even at 600°C. However, powdered beryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be 3 N 2. Beryllium oxide ...
Beryllium has also been proposed as a cladding material for nuclear fuel rods, because of its good combination of mechanical, chemical, and nuclear properties. Beryllium fluoride is one of the constituent salts of the eutectic salt mixture FLiBe, which is used as a solvent, moderator and coolant in many hypothetical molten salt reactor designs ...
Due to its physical properties, beryllium is useful as a hardening agent in alloys, making aerospace material, and used as a filter for radiation. Beryllium is not used for commercial use due to the harmful effects when it is inhaled through dust particles, causing berylliosis (a .
Mar 03, 2011· Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. Beryllium compounds are commercially mined, and the Beryllium is purified for use in nuclear weapons and reactors, aircraft and space vehicle structures, instruments, xray machines, and mirrors.
