                Product Summary of Alumina

                Alumina, also known as aluminium oxide is an electrically insulating material with relatively high thermal conductivity for a ceramic. It could be argued as being 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
