Important Facts Concerning Aluminum In NJ
Aluminum, is a chemical element with Al chemical symbol. It falls under the boron group and the name is also spelled as aluminium. The metal is relatively soft, ductile, malleable, and durable. Its appearance varies from dull gray to silver depending on the roughness of its surface. It is one of the nonmagnetic metals and does not ignite easily. There are several mining sites worldwide. Aluminum in NJ has a high level of purity and is easy to extract.
Exposing aluminium metal to air causes a reaction that forms an aluminium oxide layer on the surface. The oxide prevents corrosion because it prevents further reaction. In addition, the layer also prevents oxidation by atmospheric oxygen. Aluminium metal undergoes chemical reactions with water, aqueous salts, and acidic solutions. Its reactivity with sodium chloride and other chlorides limits its use in household plumbing.
There are several isotopes of aluminium in existence, which range in mass numbers from 21 to 42. However, of all the isotopes, only two occur naturally, these are, stable isotope (mass number 26) and radioactive isotope (mass number 27). The radioactive isotope is generated from argon in the air through the process of spallation, which results from cosmic-ray protons.
Aluminium isotopes are used in the dating of marine sediments, quartz, manganese nodules, glacial ice, and meteorites. The stable isotope in combination with Be (mass number 10) are used in studying the role of burial times, erosion, transport, deposition, and sediment storage on the 100000 and 1000000 time scales. The dating of asteroids and study of the moon are also done using the stable isotope.
Aluminium comes third when considering abundance in the crust after silicon and oxygen. It exists in form of bauxite ore. To extract the metal from the ore, the Bayer process is used. The degree of purity of ore dictates how much metal will be extracted from it. Amounts as low as a third of the whole ore are produced from the bauxite while the remaining parts are waste. Conversion of alumina into aluminium is done through the Hall-Heroult process.
Aluminium has several general uses. In fact, among non-ferrous metals, it is the most widely used metal. It is the second most produced metal worldwide after iron and its production is expected to continue growing. Aluminium is always used in form of alloys to improve its mechanical qualities. The main agents used in alloying include silicon, manganese, zinc, copper, and magnesium.
The use of aluminium is in many industries such as construction, transportation, packaging, and energy. It also makes several different household items such as siding, electronics, doors, windows, watches, and cooking ware. It undergoes chemical reaction to produce the hydrogen gas. In countries such as France, Italy, Israel, Romania, and Poland, aluminium coins have been issued to the public.
There are several health concerns related to aluminium. The metal is known to cause various conditions such as retardation in infants, allergy, digestive disorders, contact dermatitis, and reduced skeletal mineralization among others. Expression of effects of aluminium may depend on levels consumed, mode of consumption, and age among other factors.
