Information About Aluminum In NJ

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.

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.

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 entails alumina being dissolved into molten cryolite with calcium fluoride to form a compound. After fully dissolving, free aluminium ions are discharged into the molten electrolyte. Electrolytic mechanisms are then applied to reduce the compound into aluminium metal. This reduction process can only happen if the temperatures are kept in the 950 to 980 degrees Centigrade temperature range. The free aluminium ions undergo reduction process to deposit the metal at the bed. Wohler process was replaced by Hall-Heroult process. In Wohler process anhydrous aluminum chloride was reduced into aluminum using potassium metal.

This method very energy inefficient, but its application cannot be dropped because it is the most ecological and economical. The metal is able to be recycled up to 100 hundred without losing its properties. Increased manufacture of beverage cans in late 60s gave recycling a lot of importance in NJ. When recycling, scrap is melted to form an ash-like substance called dross and the pure form of the metal. With further refinement dross can be converted into the substances too.

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.

There are other uses in industries like engineering, construction, household equipment, electronics, power distribution, insulation, packaging, and lighting among many others. A reaction between the substance and hydrochloric acid or sodium hydroxide generates hydrogen gas. Powder form of aluminium is an essential additive in solid rocket fuels, certain paints, and thermite. Some states issue currencies smelt from aluminium and 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.
