Aluminium nitride is an interesting material and is one of the best materials to use if high thermal conductivity is required. When combined with its excellent electrical insulation properties, aluminium nitride is an ideal heat sink material for many electrical and electronic applications.

Silicon nitride is an extremely hard material and is very useful for applications in which physical wear is of great importance. Silicon nitride also has very good thermal shock characteristics.

Typical applications: electronic components; heat sinks; and turbine blades.
