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. |
