Is AlN ceramic?
Aluminum nitride (AlN) is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties.
What is AlN used for?
What is Aluminum Nitride? Aluminum Nitride (AlN) is an excellent material to use if high thermal conductivity and electrical insulation properties are required; making it an ideal material for use in thermal management and electrical applications.
What is AlN made of?
AlN is synthesized by the carbothermal reduction of aluminium oxide in the presence of gaseous nitrogen or ammonia or by direct nitridation of aluminium. The use of sintering aids, such as Y2O3 or CaO, and hot pressing is required to produce a dense technical-grade material.

What is the name of AlN?
Definition. Aluminum nitride, whose chemical formula is AlN, is a nitride of aluminum.
Can you machine aluminum oxynitride?
Although thin Aluminum Nitride components are fairly straightforward to machine using laser cutting techniques, machining thicker components from aluminum nitride can be extremely challenging for machining companies that do not specialize in this type of fabrication.
What is the chemical name for AlN?

What is the melting point of AlN?
3,992°F (2,200°C)Aluminium nitride / Melting point
Is aluminum nitride toxic?
Aluminum Nitride Toxicity Exposure to AlN through mouth, inhalation, or injection may cause bone and lung toxicity. Repeated exposure can irritate the eyes and skin.
Is AlN a semiconductor?
Aluminum nitride (AlN) is a III-V semiconductor with a wurtzite crystalline structure. AlN has useful properties: it has a very wide bandgap, high thermal conductivity, and high transparency of ultraviolet light.
Is AlN conductive?
Aluminum Nitride is most often the material of choice due to its relatively excellent thermal conductivity and non-toxic nature.
How is boron nitride made?
Boron nitride is produced synthetically. Hexagonal boron nitride is obtained by the reacting boron trioxide (B2O3) or boric acid (H3BO3) with ammonia (NH3) or urea (CO(NH2)2) in a nitrogen atmosphere: B2O3 + 2 NH3 → 2 BN + 3 H2O (T = 900 °C) B(OH)3 + NH3 → BN + 3 H2O (T = 900 °C)
What are the properties of ALN?
It exhibits high thermal conductivity but is, uniquely, a strong dielectric. This unusual combination of properties makes AlN a critical advanced material for many future applications in optics, lighting, electronics and renewable energy.
What is the thickness of the ALN material?
AlN commonly comes in substrates up to 1 mm thick which can easily be laser cut. It can also come in thicker forms, however, it can be difficult/costly to manufacture in small quantities if the part requires custom material or significant machining.
What is aluminium nitride ceramic?
Aluminum nitride is a refractory compound ceramic material with a hexagonal wurtzite structure. Pure aluminum nitride has a blue-white color, and aluminum nitride ceramics are usually gray or white.
