Beryllium (CAS 7440-41-7) is a grey metal that is found in nature as a mineral with silica or with aluminium and silica. Beryllium exists as a free metal or in an ionic state (Be[II]).
Beryllium metal is used:
- in structural material in space technology
- as an additive of rocket fuels
- as a moderator and reflector in nuclear reactors
- in navigational systems
- in manufacturing
Beryllium hydroxide is the feedstock for production of beryllium oxides, metal and copper beryllium master alloy.
Beryllium oxide is used in the manufacturing of:
- specialty electrical and high-technology ceramics, for example resistor cores
- special glass
- electronic heat sinks
- electron and laser tubes
- electrical insulators
- electronic components, for example circuit chip carriers
- nuclear moderators and fuels
- military vehicle armour
- rocket nozzles
- laser components
