Properties of Typical Aluminum Nitride Substrates Aluminum Nitride is becoming the material of choice for thin film, thick film and DBC applications due to its high thermal conductivity, non-toxicity, low dielectric loss and reasonable price. American Elements offers a broad range of products for hydrogen storage research, advanced fuel cells and battery applications. FREE Aluminum Nitride Technical Data Sheet . Aluminum Nitride is a versatile material most often used in situations that demand both high thermal conductivity and electrical insulation. 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. AlN was first synthesised in 1877 but it was not until the mid 1980s that its potential for application in microelectronics spurred development of high quality commercially viable material. 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. 3.26 3.32 Density measured g/cm. It exhibits high thermal conductivity but is, uniquely, a strong dielectric. It does not occur naturally. 3.24 3.30 Flexural Strength MPa 350 > 300 Young's Modulus GPa 310 310 Compressive Strength GPa 2.1 > 2.0 Fracture Toughness MPa • m. 1/2 . MECHANICAL . Hydrogen can easily be generated from renewable energy sources and is … Aluminum Nitride (AlN), a covalently-bonded ceramic, is synthesized from the abundant elements aluminum and nitrogen. It is manufactured with tightly distributed thermal and electrical properties that provide reliable performance in a … Density theoretical g/cm. Units AlN 140 AlN 180 . 3 . K) and is an electrical insulator. AlN is stable in inert atmospheres at temperatures over 2000°C. Aluminium Nitride. With the likelihood of large mechanical stresses, both during fabrication as well as in service, mechanical properties become an important aspect of overall device reliability. Ceramic Properties Standard . Aluminium nitride properties also make it particularly useful in the creation of corrosion resistant products. Aluminum Nitride is generally immediately available in most volumes. Download PDF Copy; Request Quote; Written by AZoM Jul 26 2001. It has good thermal conductivity and a small thermal expansion coefficient … 3 . Aluminium nitride is principally used in the electronics area, particularly when heat removal is an important function. Aluminium Nitride / Aluminum Nitride (AlN) - Properties and Applications. Aluminium Nitride Features & Benefits Aluminium Nitride is a high purity ceramic with superior microstructural and chemical uniformity resulting in very consistent properties. Trace Element Concentration - Typical AlN has good compatibility with Al alloy, excellent thermophysical properties, good interfacial adherence without any interfacial reaction (Kumar and Murugan, 2012), high specific strength and stiffness, high thermal conductivity, high electrical resistivity, low dielectric constant and tailorable coefficient of thermal expansion. Aluminum nitride (AlN),because of its high thermal conductivity, is seeing increased use for heat management applications of semiconductor devices. Aluminum Nitride Properties: Aluminum nitride powder can be stable up to 2200 °C and has high strength at room temperature, and the strength decreases slowly with increasing temperature. This unique ability, combined with its low toxicity, makes AIN ideal for managing rapid heating and removal of heat from other components and systems, such as in heat sinks and spreaders.
