Aluminium is one of the chemical elements under the boron category. Al is its chemical symbol and 13 its atomic number. The name can be spelt as aluminium too. Physical qualities include considerable ductility, silvery color, and softness. Aluminium comes third after silicon and oxygen gas as far as abundance in the crust is concerned. Aluminum in NJ occurs in compound form and not the highly reactive native form.
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 consumes a lot of energy, but it continues to be used because it is the most economically and ecologically viable solution. The metal is one hundred percent recyclable and it does not lose its properties when recycled. Recycling became an important activity in NJ in the late 1960s due to increased use in beverage cans. The process of recycling involves melting the scrap to form the metal and dross. Dross can be processed further to extract the element.
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.
