The aluminum nitride (AlN), one of the many phases of aluminium has high thermal conductivity and an electrical insulator. It is also resistant to attack from most molten salts. Aluminium nitride has a band gap of 6 eV at room temperature. This makes it an attractive candidate for optoelectronics.

Thermal conductivity

Besides being a high thermal conductor, aluminium nitride also has excellent electrical insulation properties. This makes aluminium nitride suitable for use as a substrate material in semiconductor manufacturing. Aluminium nitride is also a good material for high-powered electronics due to its excellent mechanical properties.

Aluminium nitride has a thermal conductivity of 319 W/m-K, with a coefficient of thermal expansion (CTE) of 4.810-6 1/K at 20 degC. It has similar thermal expansion characteristics to silicon. It also has a high resistance to thermal shock. It is resistant to molten metal corrosion and is also electrically insulating.

Reactive DC magnetron sputtering is used to produce aluminium nitride films on single-crystal silicon substrates. These films range in thickness from 150 to 3500 nm. The films are stable in hydrogen atmospheres up to 980 degC. They are also resistant to fluorine plasma attacks.

Their thermal conductivity is affected by the crystalline structure of thin films. At room temperature, for example, the band gap in the wurtzite (w-AlN), is 6 eV. The thermal conductivity of the films also changes with temperature.

Aluminium nitride cannot be blended and is highly resistant to thermal shock. Aluminium nitride is often used as a substrate material in silicon processing. It is also useful in resistor paste systems that are based on RuO2 and AgPd. It has high electrical resistivity in the range of 10-16 Om. It is also a common alternative to beryllium oxide. Because beryllium dioxide has safety and health requirements, it is a popular alternative to beryllium.

Aluminium nitride is widely used in electronic devices. It has applications in optoelectronics, semiconductor manufacturing and high power electronics. It can be used in LED lighting technology as a thermal insulator. Its thermal conductivity is similar to silicon. It is stable at high temperatures. It is resistant to thermal shock and does not fracture at high temperatures.

Because it is similar in electrical conductivity to silicon, it can be used for high-powered electronics. It is also a good substrate material for high-powered electronics.

To obtain technical-grade material, aluminum oxide must be hot pressed. It dissolves slowly in mineral acid and is highly unstable when exposed to hydrogen atmospheres.

Insulator for electrical power

Among the materials used in technical ceramics, aluminium nitride has gained a reputation for its excellent electrical insulating properties. Aluminium nitride can be used in a wide range of applications including heat sinks, circuit carriers and semiconductor circuit carriers. It has been discovered over a hundred years ago, but it was only recently that its development as a commercial product became possible.
