On this page I'll provide comprehensive data for Beryllium. I hope you profit from it.
Beryllium Overview
Name Origin
Greek: beryllos, "beryl" (a mineral).
Symbol
Be (Beryllium)Description
Hard, brittle, steel-gray metal. Lightest rigid metal. Formerly called glucinium (Gl) for its sweet but deadly taste.
Discovery
Discovered By: Fredrich Wöhler, A.A.Bussy
Year: 1798
Location: Germany/France
Sources
Found mostly in minerals like beryl [AlBe3(Si6O18)] and chrysoberyl (Al2BeO4). Pure beryllium is obtained by chemically reducing beryl mineral. Also by electrolysis of beryllium chloride.
Uses
Its ability to absorb large amounts of heat makes it useful in spacecraft, missiles, aircraft, etc. Emeralds are beryl crystals with chromium traces giving them their green color.
