Beryllium Use and Manufacturing

Source of neutrons when bombarded with alpha particles according to the equation 94Be + 42He612C + 10n.This yields about 30 neutrons per million alpha particles.Also as neutron reflector and neutron moderator in nuclear reactors.In beryllium copper and beryllium aluminum alloys (by direct reduction of beryllium oxide with carbon in the presence of Cu or Al).In aerospace, aircraft and satellite structures; x-ray transmission windows; missile parts; nuclear weapons; fuel containers; precision instruments; rocket propellants; navigational systems; heat shields; and mirrors.For fiber optics and cellular network communications systems.
