Alumina / Aluminum Oxide (Al₂O₃)

Aluminum Oxide (Al₂O₃), or alumina, is one of the most versatile refractory ceramic oxides that finds use in a wide range of applications. It is white, amorphous, and inert. It is the most common technical ceramic material used today. The versatility of alumina stems from its broadly impressive material properties, ease of manufacture, wide availability, and budget-friendly cost. It has high heat resistance, high thermal conductivity, high strength and hardness, high electrical insulation, high corrosion resistance and is biocompatible.

Purities available range from 95% (industrial grade) to 99.999% (high purity grade) and the product is also available to MIL-A-22262B.
Typical Applications

The properties of Alumina make it ideal for use in many applications. Aluminum Oxide is widely used in technical or advanced ceramics. It is used as an industrial abrasive in glass products, refractory products, and electronics. It is used throughout the medical industry for bearings in hip replacements, as prostheses, bionic implants, prosthetic eye substitutes, tissue reinforcements, and dental implants. It has applications for body and vehicle armor and in the production of bulletproof glass.

Sustainable Qualities

Alumina, also known as Aluminum Oxide, is considered a sustainable material due to its abundant availability and recyclability. It is commonly used in a variety of applications, such as ceramics, abrasives, and refractories. Alumina is derived from Bauxite, a naturally occurring mineral found in large quantities around the world. The production process of Alumina involves mining and refining bauxite ore, which can be energy-intensive. However, the material can be recycled and reused, reducing the need for virgin production and minimizing waste. In addition, Alumina is chemically inert and non-toxic, making it a safe and environmentally friendly option. Alumina also contributes to the circular economy through its potential for recycling and reuse. The material can be recycled and processed into new products, reducing the need for virgin materials and minimizing waste. Furthermore, Alumina’s durability and resistance to corrosion allow for its long-term use, reducing the frequency of replacement and extending the material’s lifespan. As such, Alumina plays an important role in promoting a circular economy by minimizing waste and reducing the environmental impact of production and consumption.
