Beryllium is a steel-gray metal that is quite brittle at room temperature, and its chemical properties somewhat resemble those of aluminum. It does not occur free in nature. Beryllium is found in beryl and emerald, minerals that were known to the ancient Egyptians. Although it had long been suspected that the two minerals were similar, chemical confirmation of this did not occur until the late 18th century. Emerald is now known to be a green variety of beryl. 1798年,法国化学家Nicolas-Louis Vauquelin在绿柱石和祖母绿中发现了铍的氧化物,1828年,德国化学家Friedrich W\u00f6hler和法国化学家Antoine A分别将铍分离出来.B. Bussy by the reduction of its chloride with potassium.<\/p>

Beryllium is widely distributed in Earth\u2019s crust and is estimated to occur in Earth\u2019s igneous rocks to the extent of 0.0002 percent. Its cosmic abundance is 20 on the scale in which silicon, the standard, is 1,000,000. The United States has about 60 percent of the world\u2019s beryllium and is by far the largest producer of beryllium; other major producing countries include China, Mozambique, and Brazil.

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.<\/p>

Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites.<\/p>

Beryllium is relatively transparent to X-rays so ultra-thin beryllium foil is finding use in X-ray lithography. Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.<\/p>

The oxide has a very high melting point making it useful in nuclear work as well as having ceramic applications.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
