High purity beryllium can be used in nuclear reactors as a moderator, reflector, or as cladding on fuel elements. [112] [113] Thin plates or foils of beryllium are sometimes used in nuclear weapon designs as the very outer layer of the plutonium pits in the primary stages of thermonuclear bombs, placed to surround the fissile material.
Sintered beryllium oxide is a very stable ceramic. [16] Beryllium oxide is used in rocket engines [citation needed] and as a transparent protective over-coating on aluminised telescope mirrors. Metal-coated beryllium oxide (BeO) plates are used in the control systems of aircraft drive devices. [17]
Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and electricity. [2] It is used for its ductility, weldability in metalworking, and machining ...
Beryllium is used mainly in military applications, [66] but non-military uses exist. In electronics, beryllium is used as a p-type dopant in some semiconductors, [67] and beryllium oxide is used as a high-strength electrical insulator and heat conductor. [68] Beryllium alloys are used for mechanical parts when stiffness, light weight, and ...

Beryl is a beryllium compound that is a known carcinogen with acute toxic effects leading to pneumonitis when inhaled. [15] Care must thus be used when mining, handling, and refining these gems. [ 16 ]
Bromellite, as a beryllium-containing mineral, has some uses. Industrially, natural specimens have the potential to be an ore of beryllium. It is one of the reagents that can be used in the manufacture of artificial emeralds. As an additive, bromellite confers high mechanical strength and very high thermal conductivity.
Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in 1815 by Jons Jakob Berzelius . [ 4 ] Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid , followed by evaporation of the solution and crystallization.
