Aluminum oxide, mainly known as the Al2o3 is one of the important engineering substance. It has the combination of all the good mechanical properties as well as the electrical properties that lead to its wide range of uses in the both industrial and domestic sectors.
The product alumina can be produced in several ranges of purities that have all the additives designed to make this product suitable for all the uses. An extensive range of ceramic methods are applied that include machining and the net shape forming for producing this product in various sizes and shapes. Additionally, it can be used with the metals or the ceramics by using the brazing and metalizing processes.
The alumina ceramic beads are one of the advanced types of ceramics in these days. Due to its wide range of utilities and properties, they are used in various purposes. There are various characteristics of the alumina that includes higher strength, excessive hardness and wear resistance, excessive thermal capacity, corrosion resistance, excellent dielectric stability and so on.
Alumina occurs naturally in the crystalline form and it is known as the corundum. This is useful in making various types of rubies and sapphires. It has the largest use in the production of the aluminum products. As aluminum is hard to touch, it is also abrasive in nature as well.
The Natural Occurrence of Alumina
The most natural crystalline formation of this material is Corundum. It forms the rubies and sapphires that are really the gem stones. The natural color of this material is due to the presence of certain impurities in them. Rubies have the bright red color due to the presence of the chromium. The sapphires are available in various colors due to the presence of the impurities in the form of titanium and iron. It has the good refractory medium and high melting point as well.
Some of the Industrial Applications Are As Follows-
The alumina is used as the filler material in the industries. It is chemically inert and it is white in color as well. It is one of the common ingredients that are used in the sunscreen mainly in the cosmetic industry. It is also used in the nail polish and in the lipsticks as well.
Alumina is also used in the paint industries for making the paint and other coloring dyes. It acts the catalyst in various chemical reactions. Hence, alumina is one of the important components and it is widely used in various purposes.
