Beryllium Element Facts

Under normal conditions, a thin layer of the hard oxide BeO forms on beryllium’s surface, protecting the metal from further attack by water or air. As a result of this BeO layer, beryllium does not oxidize in air even at 600 o C and it resists corrosion by concentrated nitric acid. Beryllium also has high thermal conductivity and is nonmagnetic
