Pure Alumina ceramics, due to their high insulation resistance at elevated temperatures, their dielectric specifications, is one of the best dielectric materials available for use in applications requiring electrical insulation.

The mechanical strength of pure Alumina ceramics may be extremely high if properly controlled by the size and homogeneity of the constituent crystallites. It is recommended to use ceramics in compression because compressive strength is nearly 10 times that of the flexural strength. This may be achieved through design or by the establishment of operating conditions.

Thermal and chemical properties of pure Alumina ceramics are always of great interest. Thermal conductivity is nearly equivalent to Stainless Steel. Pure Alumina ceramics is inert to oxidation, not corroded by chemical agents and not subjected to radiation damage.
