What is aluminum?

Aluminium (Al), a chemical element of the period 3 and group 3, has an atomic number 13. This element's electron configuration is 1s2 2s2 4p6 3s2 3p1. Its atomic weight is approximately 27 g mol-1. This element can be classified as a metal. It is actually the most abundant element in the earth's crust.

Aluminium is also a solid that is silvery white. Aluminium is durable and light. It is also low in density. It is also insoluble at room temperature in water. It also has excellent conductivity for electricity. This metal is also resistant to ignition.

Aluminiumm is also amphoteric because it has both metallic and nonmetallic properties. It can be classified as a metalloid, rather than a metal. It reacts with acids to release hydrogen gas, forming the +3-charged aluminium ion. It also reacts with hot alkali solutions to form aluminate and other nonmetallic ions.

This metal is too reactive for it to be left in its natural form so it naturally occurs in mineral forms. The main mineral containing aluminium is bauxite. It can also be found in minerals like cryolite and garnet.

Because of its low density and resistance against corrosion, this metal is most commonly used in the manufacture and construction of automobiles, other vehicles, and paints. The pure aluminium is weak and soft. However, we can add iron or silicon to improve its strength and hardness.

What is Alumina?

Alumina is an oxide of aluminum with the formula Al2O3. It is a white, crystalline solid. Aluminium is too reactive to be found in nature in its free form. Very rarely can we find Al. Aluminium oxide protects it from corrosion by being covered with oxide in nature.

Alumina's molecular weight is 102 g mol-1. It has a melting point of over 2000 degrees Celsius and a boiling point of more than 2000 degrees Celsius. This compound is also water-insoluble, but extremely hygroscopic. Alumina is also a thermal conductor, although it cannot conduct electricity. Aluminium oxide, which is also an amphoteric element is also called aluminium oxide.

Corundum is a crystalline form of alumina, and it is the most common form of alumina. It can be used to produce aluminum metal using the Hall process. This involves alumina being dissolved in molten crystallite and then electrolyzing the salt. The pure aluminum metal can then be obtained.

This compound is also abrasive because of its hardness. It can also be used as a catalyst to increase chemical reaction rates. It can also be used as a water absorber to purify gasses and filler for plastics.
