![]() ![]() Beryllium is used in the making of gyroscopes, computer equipment, watch springs and instruments where light-weight, rigidity and dimensional stability are needed.Beryllium copper is used in electrical spring contacts.In the telecommunications industry, tools made of beryllium are used to tune the highly magnetic klystrons used for high power microwave applications.These applications include the making of spot-welding electrodes, springs, non-sparking tools and electrical contacts. Beryllium-copper alloys are used in a wide variety of applications because of their combination of high electrical and thermal conductivity, high strength and hardness, nonmagnetic properties, along with good corrosion and fatigue resistance. ![]() Beryllium is used as an alloying agent in the production of beryllium copper, which contains up to 2.5% beryllium.For example, many high-quality liquid fueled rockets use nozzles of pure Be, an example being the Saturn V. Due to its stiffness, light weight, and dimensional stability over a wide temperature range, Beryllium metal is used in the defense and aerospace industries as light-weight structural materials in high-speed aircraft, missiles, space vehicles, and communication satellites.The name beryllium comes from the Greek βερυλλος, beryllos, beryl, from Prakrit veruliya, from Pāli veuriya akin or perhaps akin to Tamil language veiru or, viar, "to become pale," in reference to the pale semiprecious gemstone beryl At one time beryllium was referred to as glucinium (from Greek, sweet), due to the sweet taste of its salts (with the accompanying chemical symbol " Gl" ). Bussy independently isolated the metal in 1828 by reacting potassium and beryllium chloride. ![]() This element was discovered by Louis-Nicolas Vauquelin in 1798 as the oxide in beryl and in emeralds.
