Aluminium Oxide

aluminium oxide

Back to Encyclopedia

Initially, there were twenty elements, which were referred to, as the first twenty elements in the periodic table. Then scientists went further and discovered up to a hundred more complex elements. Not only do we have hundred now, but we can combine these elements to produce compounds that are not just for use by the scientists alone but by common, everyday people.

Aluminium, being the 13th element and Oxygen, the 8th element in the periodic table are two elements that have high affinity for each other. These elements, when combined through ionic bonding serve lots of purposes, especially in the production of some of our human necessities.

Aluminum oxide, which is usually called alumina is a compound, which has a chemically powerful ionic bond, which in turn brings about its attractive material features. This oxide is amphoteric in nature and has the chemical configuration of Al2O3. In its crystalline form, it is referred to as corundum and still has various names showing its widespread availability in the environment and industry.

Properties of Aluminium Oxide

Alumina has a lot of features, some of which include:

1. Although Aluminium oxide has a moderately high ability to conduct heat (30 Wm−1K−1) in a ceramic material, it serves as an excellent electrical insulator.

2. Aluminium oxide is hard in its crystalline form, this makes it appropriate to act as a coarse substance or abrasive also in cutting tools.

3. Aluminium serves as a reliable roofing sheet because aluminium oxide is helps to prevent the metallic aluminium from atmospheric conditions and weathering.

Aluminium oxide can be applied in many ways, some of which include:

· Aluminium oxide can be used to fill plastics and is also used in cosmetics.

· It is used as a vehicle and for dehydrating alcohols to form alkenes.

· It is used to purify gas by removing the water.

· It can be used as sandpaper due to its coarse nature and strength.

Newer ways to apply aluminium oxide are yet to be discoveredbut they will be to the benefit of mankind.
