The Aluminum Oxide and Nitric Acid Equation

Whether you are in the mining industry or a ceramic community, you are likely to come across aluminium oxide. It is a white crystalline compound that has a chemical composition of Al2O3 (Al is a member of the group of metals called period III).

The compound is used as a chemical oxidant, a fire retardant, and a zeolite pigment. It also serves as a support for many industrial catalysts, including Ziegler-Natta polymerizations. It is also used as a substrate for integrated circuits. Moreover, it is used in the Claus process and serves as a tunnel barrier for superconducting devices.

Aluminum oxide can be produced in seven different crystalline forms. The most common is corundum, which adopts a trigonal Bravais lattice. It is also the only thermodynamically stable form. The other crystalline forms are k-Al2O3 (3,77 g/cm3), p-Al2O3, and n-Al2O3.

The chemical reaction between aluminum and nitric acid is an endothermic gas-phase reaction. During this reaction, a dense layer of oxide forms on the surface of the aluminum. The oxide prevents the aluminum from further reacting with the oxide.

Nitric acid is a strong oxidizing agent. It reacts with other metals, acids, halogens, and bases. It is also used to neutralize aluminum oxide. It is also known as aqua fortis or strong water.

Nitric acid has a reddish-brown color. It is stored in aluminium containers. It has a plus five oxidation state for nitrogen. Moreover, it has five electrons in its valence shell. Its oxidizing property is strong and it reacts with all types of metals and non-metals. It is also used for fertilizer production.
