Alumina is used to manufacture tiles which are attached inside pulverized fuel lines and flue gas ducting on coal fired power stations to protect high wear areas. They are not suitable for areas with high impact forces as these tiles are brittle and susceptible to breakage.

What are the disadvantages of alumina?

One of the main disadvantages of Al₂O₃ ceramic is its brittleness. It is prone to fracture upon impact, which can limit its lifespan in applications subjected to mechanical shocks. Due to its high hardness, alumina ceramic is challenging to process, requiring specialized equipment and techniques.

Alumina can be produced in a range of purities with additives designed to enhance properties.

A wide variety of ceramic processing methods can be applied including machining or net shape forming to produce a wide variety of sizes and shapes of component. In addition, it can be readily joined to metals or other ceramics using metallising and brazing techniques.

Alumina based ceramics are by far the largest range of advanced ceramics made by Morgan Technical Ceramics. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our alumina products to give you the best possible component.

Typical alumina characteristics include:
Good strength and stiffness
Good hardness and wear resistance
Good corrosion resistance
Good thermal stability
Excellent dielectric properties (from DC to GHz frequencies)
Low dielectric constant
Low loss tangent
