Beryllium is a silvery-white metal. It is relatively soft and has a low density. Uses. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
Beryllium oxide, commonly known as beryllia, has the chemical formula BeO and is a white, amorphous solid in its pure form. The compound was originally named glucina (because of its sweet taste) and occurs in nature as the mineral bromellite. It is amphoteric, meaning it can act as either an acid or a base.

of beryllium oxide has been the subject of several theo-retical studies [15, 27, 49–52]. The results suggest that the Ç4 Ç1 phase transition should be expected to occur in the range 40 to 147 GPa. Also possible is a wurtzite-to-sphalerite (Ç3) phase transition [26, 49– 52]. Its pressure has variously been estimated at 63 to 91 GPa [51–53].

Beryllium is primarily used in its metallic form, in alloys, or in beryllium oxide ceramics. Its physical and mechanical properties make it useful for many applications across a range of industries. These properties include: outstanding strength (when alloyed), high melting-point, high specific heat, ...
Alternatively, the hydroxide can be heated to form the oxide, which in turn can be treated with carbon and chlorine to form beryllium chloride; electrolysis of the molten chloride is then used to produce the metal. The element is purified by vacuum melting. Beryllium is the only stable light metal with a relatively high melting point.

Similarly, in the presence of a strong base, beryllium and its salts form the tetrahedral hydroxo complex: [Be(OH) 4] 2−. Hence beryllium oxide is amphoteric. Beryllium also forms a very stable tetrahedral fluoride complex: [BeF 4] 2−. Recall that beryllium halides behave like Lewis acids by forming adducts with Lewis bases …
