Aluminium oxide, also known as alumina, is a chemical compound of aluminium and oxygen with the chemical formula Al2O3 . In the context of commercial construction in Australia, aluminium oxide is defined as a material that, when further refined, produces aluminum .
Properties and Uses
Aluminium oxide has several properties that make it suitable for use in commercial construction in Australia:
- It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air, which acts as an excellent corrosion barrier .
- It is used as an adsorbent, desiccating agent, and catalyst .
- It is a key component in the production of aluminum, which is used in various construction materials, such as aluminum framing, roofing, and cladding.
In Australia, the use of aluminium oxide in commercial construction is subject to various standards and regulations, including the Australian Standard AS 2879.7—1997, which outlines the methods for determining trace elements in alumina using wavelength dispersive X-ray fluorescence spectrometry .
One of the primary uses of aluminum oxide in commercial construction is as a component of ceramic tiles and other building materials. Aluminum oxide is added to ceramic tiles to improve their strength, durability, and resistance to wear and tear. It also enhances the tiles' resistance to chemicals, making them suitable for use in high-traffic areas such as bathrooms and kitchens.
Aluminum oxide is also used as a protective coating on various building materials, including concrete, steel, and wood. This coating provides a barrier against moisture, corrosion, and other environmental factors, helping to extend the lifespan of the underlying material.
