Toxicity And Beauty Of Beryllium
Beryllium is the lightest member of the alkaline earth metals family. Beryllium was discovered by French chemist Louis-Nicolas Vauquelin in 1798. Vauquelin suggested the name glucinium, meaning "sweet tasting," for the element because the element and some of its compounds have a sweet taste. The name beryllium was adopted officially in 1957. Beryllium- copper alloys account for about three-quarters of all the beryllium produced.
A common compound of beryllium, beryl, was known in ancient Egypt, but nothing was known about the chemical composition of this mineral until the end of the eighteenth century. In 1797, French mineralogist René-Just Haüy completed studies on beryl and emerald. Emerald is a naturally occurring green gemstone. Haüy was convinced that these two minerals were nearly identical. He asked a friend, Vauquelin, to determine the chemical composition of the two minerals.
When Vauquelin performed his chemical analysis, he found a new material that had been overlooked because it is so much like aluminum. His data proved that the material was not aluminum. He suggested calling the new element glucinium. Scientists referred to the element by two different names, beryllium and glucinium, for 160 years. The name beryllium comes from the mineral, beryl, in which it was first discovered. With melting point of 1,287°C (2,349°F), boiling point of 2,500°C (4,500°F), and density of 1.8 grams per cubic centimeter, beryllium is a hard, brittle metal with a grayish-white surface. It is the least dense (lightest) metal that can be used in construction. The metal has a high heat capacity (it can store heat) and heat conductivity (it can transfer heat efficiently).
Interestingly, beryllium is transparent to X- rays. X rays pass through the metal without being absorbed. For this reason, beryllium is sometimes used to make the windows for X-ray machines. Beryllium reacts with acids and with water to form hydrogen gas. It reacts briefly with oxygen in the air to form beryllium oxide (BeO). The beryllium oxide forms a thin skin on the surface of the metal that prevents the metal from reacting further with oxygen. Beryllium never occurs as a free element, only as a compound. The most common ore of beryllium is beryl. Beryl has the chemical formula Be 3 (Al2 (SiO3))6.
The major beryl producer in the world is the United States. The only mine currently producing beryl is in Delta, Utah. Beryl is also converted to beryllium and its compounds in plants in Delta; Elmore, Ohio; and near Reading, Pennsylvania. Beryl is also obtained from mines in China, Russia, and Brazil. Beryllium is relatively common in the Earth's crust. Its abundance is estimated at 2 to 10 parts per million.
Only one naturally occurring isotope of beryllium: beryllium-9exists. Six radioactive isotopes of beryllium are also known. None of the isotopes of beryllium has any commercial use. Beryllium ores are first converted to beryllium oxide (BeO) or beryllium hydroxide (Be(OH)2). These compounds are then converted to beryllium chloride (BeCl2) or beryllium fluoride (BeF2). Finally, the pure metal is isolated by either an electric current or by reaction with magnesium metal at high temperature.
By far the greatest use of beryllium metal is in alloys. Beryllium alloys are popular because they are tough, stiff, and lighter than similar alloys. For example, a new alloy of beryllium and aluminum called Beralcast was released in 1996. Beralcast is 3 times as stiff and 25 percent lighter than pure aluminum. The maker of Beralcast expects sales of $20 million from its use in helicopters and satellite guidance systems.
The most popular alloys of beryllium at the present time are those with copper metal. Copper-beryllium alloys contain about 2 percent beryllium. They conduct heat and electricity almost as well as pure copper but are stronger, harder, and more resistant to fatigue (wearing out) and corrosion (rusting). These alloys are used in circuit boards, radar, computers, home appliances, aerospace applications, automatic systems in factories, automobiles, aircraft landing systems, oil and gas drilling equipment, and heavy machinery. Fifteen percent of the beryllium used in the United States is in the form of beryllium oxide (BeO). It is a white powder that can be made into many different shapes. It is desirable as an electrical insulator because it conducts heat well, but an electrical current poorly. It is used in high-speed computers, auto ignition systems, lasers, microwave ovens, and systems designed to hide from radar signals.
Beryllium is a very toxic metal. It is especially dangerous in powder form. The effects of inhaling beryllium powder can be acute or chronic. Acute effects are those that occur very quickly as the result of large exposures. Chronic effects are those that occur over very long periods of time as the result of much smaller exposures. Acute effects of inhaling beryllium powder include pneumonia-like symptoms that can result in death in a short time. Chronic effects include diseases of the respiratory system (throat and lungs), such as bronchitis and lung cancer.
Purity is not always desirable, at least not for gemstones. A gemstone is a mineral that can be cut and polished for use in jewelry. Some typical gemstones are jade, sapphire, diamond, ruby, amethyst, emerald, spinel, moonstone, topaz, aquamarine, opal, and turquoise. Gemstones are often used as birthstones, which honor the month in which a person is born. (For instance, the birthstone for April is a diamond.) Gemstones are valued for their beautiful colors and crystal forms. Light reflects off them in brilliant patterns. The crystal forms are the result of very exact arrangements of atoms in the gemstone. Its perfection contributes to its beauty and its monetary value.
But gemstone color is due to very small impurities in the mineral. For example, the mineral known as corundum is colorless when pure. But a very small amount of chromium produces a bright red color. The corundum is now a ruby. A touch of iron or titanium produces shades of yellow, green, purple, pink, or blue that turn it into a sapphire.
Two gemstones are made primarily of beryl. They are emeralds and aquamarines. In emeralds, traces of chromium produce a brilliant green color. In aquamarines, iron is the impurity. It gives the beryl a beautiful blue color. These effects can be avoided fairly easy. Workers can wear masks over their faces to filter out beryllium particles. Filtering devices in factories where beryllium is used also prevent beryllium from getting into the air.

Alloy king rc helicopter.........?
I just got an rc helicopter but it came with no directions on how to fly it.... we have tried to fly it twice now but only broke propellers before it left the ground. I was wondering if i just shot it off into the air then get it level from there..... If you know anything about these please answer!!!!!!!!!!
I answered you earlier. I told you to go to your local RC club and ask for help learning to fly it. You then sent me an email asking how to contact them. I reply-ed by saying to go ask the employees at your local hobby store, as the club members are the customers at the hobby store. If your lucky, one of the employees at your hobby store will actually be a club member.
