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
One cubic foot of steel weighs about 490 lb; a cubic foot of aluminum, only about 170 lb.
By far, most manufactured beryllium (about 75%) ends up in alloys, approximately 95% of which is copper alloy. Beryllium alloys with metals such as copper, nickel, or aluminium have high strength and hardness. They typically contain 0.15–2.0% beryllium.
Aluminium-beryllium metal matrix composite combines the high modulus and low density characteristics of beryllium with the fabrication and mechanical property behaviors of aluminium. Due to weight advantage, Be-Al alloys are used in aerospace and satellite applications.
