Beryllium
General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to act as a source, moderator and reflector of neutrons. It can be forged, rolled and extruded, machined, punched, sheared and casted by vacuum casting. Commercially, it is available in block, rod, sheet, pebble, metal disk, foil and powder form.

It can withstand fatigue and wear, and can be strengthened and hardened to an accurately controllable degree. It can be easily casted, corrosion resistant and reproduce fine detail. Moreover, it has high electrical conductivity at high temperatures. To introduce Beryllium into metals, Beryllium alloys of magnesium-aluminum, aluminum, nickel, copper, iron or cobalt are always used (Hornbostel, 1991). According to Harper (2001), Beryllium oxide, with a melting point of 2585 °C and specific gravity of 3.025, is a cubic close-packed and has a zinc blende structure. It is stable in dry atmospheres. At high temperature, it reacts with graphite. And for 1100 °C and above, it hydrolyzes. It is electrically resistant and is a good thermal …show more content…
It also used to eliminate the use of lead and cadmium and minimize the use of zinc and nickel. Also, it is used in immersion deposition for all surface replaceable ions to become tin. However, to attain good results, a good base metal preparation is needed. It is an environment-acceptable process and has a low cost. In electrodeposition, it is used as an alternative for tin-lead and cadmium coatings due to its good solderability and corrosion resistance. But, formation of thin whiskers can also be observed. It can also be used in hot dipping, autocatalytic deposition and spraying (Harper,

    Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4, the excess ethyl vinyl ether was removed by rotary evaporation.…

    Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France.…

    Palladium is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. He named it after the asteroid Pallas, which was it’s named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium. Over half of the supply of palladium and its congener platinum goes into catalytic converters, which convert up to 90% of harmful gases from auto exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less-harmful substances (nitrogen, carbon dioxide and water vapour).…

    How The Shakespeare Ugly Stik Got Its Name During the 1940s, fishing rods were made of either hollow or solid fiberglass. Hollow fiberglass fishing rods were lighter and more affordable than solid versions, but they were more brittle and subject to breakage, particularly the tip. The solid rods were stronger, but they were also heavier and more expensive than the hollow ones. Shakespeare developed a process that consolidated the benefits of each type of rod by joining a hollow fiberglass base to a solid fiberglass tip.…
