            Custom-made Ceramic
            and Glass Components


            Aluminum oxide (Al2O3), commonly known as alumina, is extensively used as an engineering ceramic due to its high performance at a cost-effective price. Typically, alumina is available in grades from 88% to 99.99% purity with properties varying accordingly. Zirconia-toughened alumina is a modified, stronger grade of alumina.

            Alumina components can be manufactured by a number of different methods including pressing, extruding, slip casting and injection molding.  The method of manufacture generally depends on the size and quantity of components required. 

            Alumina starts the manufacturing process as a powder which, once compressed, can be machined if required (known as “green machining”) before being fired. After firing, further processing can only be carried out using diamond tooling.

            It could be argued that alumina is one of the most cost-effective of all ceramic materials, and as a result is one of the most widely used. Its combination of high thermal conductivity and low thermal expansion imparts good thermal shock resistance.

            Characteristics of alumina include:

            • Electrically insulating
            • High thermal conductivity
            • High strength and stiffness
            • Available in a range of purities
            • Excellent resistance to strong acids and alkalis at elevated temperatures
