Aluminium Oxide Ceramic Uses

Alumina ceramics have a wide variety of uses. They are the most common technical ceramics and offer a combination of mechanical strength, electrical insulation and corrosion resistance. They are available in a range of compositions with alumina content up to 95% and a broad spectrum of color options. They have excellent permeability to visible light and infrared rays. They also have good dielectric properties, low loss tangent and stiffness. These qualities are important for high-frequency electrical applications such as electronic substrates and insulators.

Moreover, these materials have high thermal conductivity and good chemical stability at both room and elevated temperatures. They are also hard, second only to diamond on the Mohs scale of mineral hardness. In addition, alumina has very good abrasion and wear resistance properties. This makes it an ideal material for abrasive grinding wheels, cutters and dies. It is used in abrasion-resistant industrial components such as textile guides, crusher liners, acid-carrying pump impellers and discharge orifices. It is also a popular choice for making spark plugs.

The alumina ceramics produced by Ortech are well-known for their superior material quality, high performance and excellent durability. The company maintains state-of-the-art manufacturing facilities that support quick-turn prototype development and high volume production. These processes are key to delivering products that meet the most stringent customer requirements. They can be fabricated through many methods of consolidation including extrusion, uniaxial and isostatic pressing, slip casting and injection molding. The alumina ceramics can then be plated with a variety of coatings to provide different functionalities.
