Beryllium: Chemical reactions | Pilgaard Elements

Beryllium is passivated by oxygen, forming a BeO surface which is resistant to acid. On a fresh surface, without the protective layer, beryllium dissolves readily in dilute acids such as sulphuric acid, H 2 SO 4, hydrochloric acid, HCl, and nitric acid, HNO 3, forming Be(II) ions and hydrogen gas, H 2. Ba (s) + 2 H + (aq) Ba 2+ (aq) + H 2 (g)

Guide to Copper Beryllium - Matthey

Copper beryllium's physical and mechanical properties differ considerably from those of other copper alloys because of the nature and action of the alloying ele-ments, principally beryllium. Varying the beryllium content from about 0.15 to 2.0 weight percent pro-duces a variety of alloys with differing physical properties.

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.
