Properties and uses of elements of the family aluminum

Aluminum is lightweight, silvery metal, familiar to all households in the form of pots and pans, beverage cans, aluminum foil and. Interestingly, non-toxic, resistant to corrosion, nonmagnetic, and easy to train, cast, or machine in a variety of forms. Aluminum is the third most abundant element in Earth's crust after oxygen and silicon, and is the most abundant of all metals. It constitutes 8.1 percent of the crust by weight and 6.3 percent of all atoms in the crust. Because it is a very active metal, aluminum is never found in its metallic form. Instead, it occurs in a wide variety of earthy minerals and rocks. Kaolin is particularly beautiful, white, aluminum-containing clay is used in the manufacture of china. Known as the aluminum in the other Anglo-Saxon element was named after alum mineral salt thereof which have been known for thousands of years. Alum has been used by the Egyptians, Greeks and Romans as a mordant, a chemical that helps dyes stick to cloth.

Pure aluminum is soft and not a solid metal. When merging with many other elements, it forms alloys with a wide range of useful properties. Aluminum alloys are used in aircraft, road signs, bridges, storage tanks, and buildings. The world's tallest buildings, towers of the World Trade Center in New York are covered with aluminum. Aluminum is increasingly used in cars, because only one third heavier than steel and therefore fuel consumption decreases.

Despite the fact that aluminum is chemically very active, it does not corrode in humid air the track does. Instead, it quickly forms a thin layer hard coating of aluminum oxide. Unlike iron oxide or rust, flaking, aluminum oxide sticks well for the metal and protects it from further oxidation. The oxide layer is so thin that it is transparent, then the aluminum retains its appearance silver metallic. Seawater, however, damage aluminum unless it has been given a unusually thick coating of oxide by anodization process during the anodizing process, a piece of aluminum is oxidized in order to create a layer of aluminum oxide on its surface, which is capable of making dyes, in contrast to the raw aluminum.

When aluminum is heated to high temperatures in vacuum, it evaporates and condenses on any surface Nearby cool as glass or plastic. When evaporated on a glass, it makes a very good mirror. The aluminum has largely replaced the money in the production of mirrors, because it does not tarnish and turn black money does when exposed to impure air. Many packaging materials plastic food brilliant innovations are made of paper or plastic with a coating of evaporated aluminum finish. Helium balloons color silver-popular birthday parties are made of hard plastic, covered with a thin metal evaporated coating of aluminum. Aluminum is one of the best conductors of electricity, with a conductivity of about 60 percent that of copper. Because is also very lightweight and ductile (able to be fired in thin son), it is used instead of copper in almost all high-voltage lines transmission in many countries.

Aluminum is used for cookware because of its high thermal conductivity. It is handy as a waterproof and water-food packaging because it is very malleable, it can be pressed between steel rollers to leaf (A thin sheet) less than one thousandth of an inch thick. The claims are sometimes made that aluminum is toxic and batteries aluminum cooking is dangerous, but no clear evidence of this belief has never been solved. Much more widely used nonprescription antacids contain thousands of times more aluminum (as aluminum hydroxide) that nobody could ever get to eat food cooked in an aluminum pot. Aluminum is the only light that has not experienced a physiological function in the human body.

As a metal very reactive, aluminum is very difficult to separate other elements that are combined with it in its minerals and compounds. Despite its abundance on Earth, the metal itself has remained unknown for centuries. In 1825, some impure aluminum metal was finally isolated by the Danish physicist Hans Christian Oersted in treating aluminum chloride with potassium amalgam (potassium dissolved in mercury). Then, in 1827, the chemist German Hans Wöhler obtained in pure aluminum by the reaction of potassium metal with aluminum chloride. It is generally given credit for the discovery of elemental aluminum.

But it was still very expensive to produce aluminum metal in any how much and for many years it remained a rare metal and precious. The big breakthrough came in 1886 when Charles M. Hall, a student of 23 years Oberlin College in Ohio, and Lt. Paul. Heroult, another student in France independently invented what is now known as the hall or Hall-Heroult. This method involves dissolving alumina (aluminum oxide) in molten cryolite, a common mineral containing aluminum, and then pass an electric current through the hot liquid. The molten aluminum collects at the cathode (negative electrode). Shortly after the development of this process, the price of aluminum metal has dropped about 30 cents a pound. The process used to extract aluminum from its ores today is essentially the same as that developed by Hall and Héroult 150 years ago.

elemental boron occurs in a variety of forms ranging from light to red crystals of a black powder or brown with a black transparent crystal that is almost as hard as diamond. Element never found free in nature but is extracted commercially from minerals such as borax, ulexite, colemanite, and kernite. Boron is a relatively rare element, constituting about 0.001 percent of Earth's crust. It is ranked number 38 in abundance, after nitrogen, lithium and lead, but before bromine, uranium, and tin.

The physical properties of boron are quite difficult to determine because the element is in a multitude of different forms. Chemically boron is a fascinating element. A text on claims that the chemical elements in inorganic chemistry Boron is "more diverse and more complex than any other element of the periodic table. The element forms five types of compounds: (1) metal borides (boron over a metal), (2) boron hydrides (boron more hydrogen), (3) trihalides boron (boron plus a halide, halide is a single-halogen), (4) oxo compounds (boron complex oxygen radicals, a radical is a group of atoms which behaves as a unit in chemical reactions, but is not stable except as part of the enclosure), and organic compounds of boron (boron combined with an organic or carbon-containing component).

Boron itself has relatively little used outside of its role in nuclear reactors as a neutron absorber in alloys and as a hardening agent. It is also used in the manufacture of semiconductors. His best known compound, borax is used as a water softener in the production of glass and ceramics, and as a herbicide. A compound derived from borax, boric acid, is used as an eyewash and the production of heat resistant glass. boron carbide and boron nitride are two boron compounds of interest particular. Both are used as refractory materials, substances which are highly resistant to heat. When the boron nitride powder is compressed at very high pressures, it produces a hard, crystalline, which is harder than natural diamond.

For most of its history, the gallium is best known for an unusual physical property: it has a melting point of 29.76 ° C (85.6 ° F) lower than that of the human body. If we have was to hold a piece of metal gallium in hand, it would melt. Despite this fact, gallium and its compounds have always had few uses until recently. In 1970, a compound of gallium arsenide gallium called was found to have properties of semiconductors. Gallium arsenide has also been widely used in light emitting diodes (LEDs), which are used in electronic displays calculators, watches and CD players. Neither indium nor thallium has many commercial applications. The first element is used mainly in manufacture of alloys and the production of transistors and photocells. A radioactive isotope of the latter, thallium-201 is used in studies of medical diagnosis, especially those involving the function of the circulatory system.
