Aluminum Nitride Ceramic

Its wurtzite phase w aln has a band gap of 6 ev at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies.

Aluminum nitride ceramic. However it also provides electrical insulation. We present the machinable ceramic shapaltm hi m soft manufacturer tokuyama corporation came to market in early 2012 design. Beryllium oxide beo and cubic boron nitride c bn are virtually the only other examples. However the sintering process that is required to fully densify the material causes the aluminum nitride body to shrink approximately 20.

Aluminium nitride al n is a solid nitride of aluminium. The machine generated ceramic is designed so that a high mechanical strength combined with high thermal conductivity is achieved and is a sintered composite of boron nitride and aluminum nitride ain bn. Only a few ceramics possess high thermal conductivity. Aluminum nitride aln is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties.

However the use of beo is restricted due to its toxicity and c bn is. Aluminium nitride has the highest thermal conductivity of any ceramic material on a par with most metals. 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. It is four times harder than fused silica glass 85 as hard as sapphire and nearly 15 harder than magnesium.

We combine expansive technical understanding with a commitment to working with customers ensuring that our material solutions meet exacting specifications whilst providing exceptional performance. Aluminum nitride formula aln is a newer material in the technical ceramics family. While in the green or biscuit form it can be machined relatively easily into complex geometries. Aluminium nitride is a high performance material particularly suited to demanding electrical applications.

1 when choosing ceramic base material pcbonline always select ceramic materials with stable chemical properties high temperature resistance strong acid and alkali resistance high thermal conductivity and many good qualities and strictly uses 96 alumina ceramic base board and 101 aluminum nitride ceramic base board to ensure the long service life and high stability of your ceramic pcb. Aluminium oxynitride or alon is a ceramic composed of aluminium oxygen and nitrogen it is marketed under the name alon by surmet corporation. Non oxide ceramics aluminum nitride aln ceramic material with very high thermal conductivity. Aluminum nitride aln is a unique ceramic material that combines high thermal conductivity with high electrical resistivity.

Aluminum nitride machining grinding. Aluminium nitride fully sintered and machinable aluminium nitride aluminium nitride is a specialist material for the most demanding applications. Aluminum nitride ain ceramic properties.
