BERYLLIUM, or Glucinum (symbol Be, atomic weight 9.1), one of the metallic chemical elements, included in the same sub-group of the periodic classification as magnesium. It was prepared in the form of its oxide in 1798 by L. N. Vauquelin ( Ann. de chimie, 1798, xxvi. p. 155) from the mineral beryl, and though somewhat rare, is found in many minerals.

Beryllium, Physical and Chemical Properties SpringerLink

Beryllium is the first member of the alkaline earths but its chemical properties are more similar to aluminum – a property described as “diagonal similarities” (Fig. 1) as discussed below. Beryllium is an expensive metal used in small and specialized industries. Its dust and fumes as well as vapours of its compounds are poisonous to inhale.

Beryllium carbide chemical compound Britannica

The best-characterized methanides are probably beryllium carbide (Be 2 C) and aluminum carbide (Al 4 C 3). Beryllium oxide (BeO) and carbon react at 2,000 °C (3,600 °F) to produce the brick-red beryllium carbide, whereas pale yellow aluminum carbide

Beryllium Disease - ILO Encyclopaedia

Beryllium disease is a systemic disorder involving multiple organs, with pulmonary manifestations being most prominent and common. It occurs on exposure to beryllium in its alloy form or in one of its various chemical compounds. Route of exposure is by inhalation and the disease can be either acute or chronic.

Beryllium carbide - Wikipedia

Beryllium carbide is prepared by heating the elements beryllium and carbon at elevated temperatures (above 900°C). It also may be prepared by reduction of beryllium oxide with carbon at a temperature above 1,500°C: 2BeO + 3C → Be 2 C + 2CO. Beryllium carbide decomposes very slowly in water: Be 2 C + 2H 2 O → 2BeO + CH 4

Beryllium - an overview ScienceDirect Topics

Beryllium is an amphoteric metal forming the strongly acidic Be 2+ and alkaline BeO 2 2− under different conditions. Beryllium metal, carbonate, hydroxide, phosphate, and acetate dissolve in acids or alkalines. Beryllium also shows a very high affinity for oxygen, which predisposes it to the formation of insoluble phosphates (ATSDR 2002).
