Aluminium is a chemical element grouped under the boron group. It is also spelt as aluminium and its chemical symbol is Al while the atomic number is 13. Physical properties include silvery color, softness, and considerable ductility. Aluminium has high abundance in terms of the composition of the crust of the earth and it comes third after oxygen and silicon. Aluminum in NJ does not occur in its native form because it is highly reactive.
Under natural situations, the ore exists as a mixture of more than 270 other minerals. Bauxite is the primary ore. The most significant characteristics of the substance are low density and resistance to corrosion. Low density is useful in the construction of aircrafts and structural components. Rusting does not occur in the metal rendering it useful in several industries.
In NJ, aluminium is produced through a couple of ways. The most used industrial method is referred to as Hall-Heroult process. Other methods include electrolytic smelting of alumina and indirect carbothermic reduction. Indirect carbothermic reduction method is more effective though it is not yet fully developed. It requires less energy and produces less Carbon monoxide gas compared to the Hall-Heroult process.
Hall-Heroult process requires alumina to be dissolved into molten calcium fluoride with cryolite. After completely dissolving, aluminium ions are released into the electrolyte to move freely. Electrolytic means are then used to reduce the resultant compound into aluminium. For this reduction to happen, the temperatures must be kept in the range of 950 and 980 degrees Centigrade. Aluminium ions undergo reduction depositing the metal at the bottom. Hall-Heroult process took the place for the Wohler process. Wohler process used potassium metal to reduce anhydrous aluminum chloride into aluminum.
This method requires large amounts of energy, but its use cannot be abandoned because it provides the most ecologically and economically viable option. The metal can be recycled up to one hundred percent and its properties do not get lost upon recycling. The increased production of beverage cans in NJ in late 1960s made recycling a very important activity. Recycling entails melting scrap to create pure metal and an ash-like deposit called dross. With further processing the element can be derived from dross.
The recycled form is known as secondary aluminum although its applications and properties and those of the primary aluminium are similar. To make the mechanical characteristics of the metal better, it is used as an alloy in most cases. The alloys sometimes comprise of manganese, copper, magnesium, silicon, and zinc. Main application is in the construction of transport vessels like railway cars, aircrafts, marine vessels, and trucks.
Other uses are in industries such as packaging, lighting, engineering, construction, household items, electronics, power distribution, and insulation among others. Reacting the substance with hydrochloric acid or sodium hydroxide produces hydrogen gas. Powdered form is a vital additive in thermite, solid rocket fuels, and certain paints. Some states have and continue issuing currencies made from aluminium or its alloys.
Research has not shown any severe medical concerns resulting from consuming small amounts. Consuming large quantities however might cause neurotoxicity and other problems in the nervous system and brain. When people who are allergic make contact with it, they may experience contact dermatitis, digestive disorders, and vomiting.
