To view the original source information, use the "Learn more" links.Aluminum oxide is an ionic compound formed from an electrostatic bond between two aluminum atoms which have lost 3 electrons each (Al 3+) and three oxygen atoms which have gained 2 electrons each (O 2-). The strength of the ionic lattice is a function of the individual ionic charges and their radii.www.ceramicsrefractories.saint-gobain.com/news-…Oxygen typically catalyses corrosion in reaction with the metal aluminium. However, when bonded with oxygen to form aluminium oxide, a protective coating forms and prevents further oxidation. This adds strength and makes the material less vulnerable to deterioration.matmatch.com/learn/material/aluminium-oxide
