Aluminum Nitride Ceramic

Aluminum nitride sheet description.

Aluminum nitride ceramic.

Beryllium oxide beo and cubic boron nitride c bn are virtually the only other examples. Aluminum nitride formula aln is a newer material in the technical ceramics family. Aluminum nitride is stable at high temperatures in inert atmospheres and melts at 2800 c. Due to its high thermal conductivity and great electrical insulation aln was used in microelectronic industries.

Aluminum nitride is a refractory compound ceramic material with a hexagonal wurtzite structure. Dear visitor our homepage is currently undergoing a rebuilding phase which may lead you back and forth between our old and our new design. Only a few ceramics possess high thermal conductivity. Utilizing this feature they are used in components for semiconductor manufacturing equipment substrate materials and fillers and more as their applications are expanding.

Alumina nitride sheets are made of high purity aluminum nitride ceramics aln is a light grey or white ceramic material which has a density of 3 26g cm3. Aluminium nitride features benefits. Aluminum nitride aln combining excellent thermal conductivity and high thermal shock resistance with superior electrical insulation aluminum nitrides provide electrical insulation while also dissipating heat effectively in applications where other ceramics are prone to thermal shock. Aluminum nitride ceramics are highly thermal conductive thermal radiative and have a good electrical insulation property.

It is manufactured with tightly distributed thermal and electrical properties that provide reliable performance in a variety of applications. Pure aluminum nitride has a blue white color and aluminum nitride ceramics are usually gray or white. Aluminium nitride can be produced by dry press and sinter or by hot pressing with appropriate sintering aids the result of these processes is a material that is stable at high temperatures in a range of inert environments including hydrogen and carbon dioxide atmospheres. Aluminum nitride ain ceramic properties.

While its discovery occurred over 100 years ago it has been developed into a commercially viable product with controlled and reproducible properties within the last 20 years. Aluminum nitride aln is a unique ceramic material that combines high thermal conductivity with high electrical resistivity. Aluminum nitride aln is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. Aluminum nitride with high thermal conductivity over 200w m k was obtained by millimeter wave sintering at low temperature of 1700 c for 2hrs under nitrogen hydrogen.
