Aluminium refers to a chemical element under the boron group. It has a chemical symbol of Al with 13 as the atomic number. It is also spelt as aluminium. Physical characteristics include softness, considerable ductility, and silvery color. Aluminium comes third in terms of abundance in the crust of the earth after silicon and oxygen gas. Aluminum in NJ occurs in a mixed form and not the native form because of high reactivity.
Naturally, the ore exists in combination with over two hundred and seventy other minerals. Bauxite forms the primary ore. Most profound characteristics of aluminum are ability to resist corrosion and low density. Low density becomes useful in the manufacture of structural components and aircrafts. Because the metal does not rust, it is very useful in various industries.
There are numerous ways in which aluminium is produced in NJ. The main one is called the Hall-Heroult process. Others include indirect carbothermic reduction and the electrolytic smelting of alumina. Although still under development, indirect carbothermic reduction is proving to be very effective. It generates less Carbon (II) Oxide gas while consuming less power when compared to 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.
