For procurement managers, R&D scientists, and product formulators in the B2B chemical and pharmaceutical sectors, understanding the properties of advanced materials is crucial for making informed purchasing decisions. Aluminum Nitride (AlN), identified by CAS 24304-00-5, is a ceramic material that offers a unique and highly desirable set of properties, making it indispensable in demanding applications across electronics, semiconductors, and thermal management.

Decoding the Properties of Aluminum Nitride (AlN)

Aluminum Nitride is a synthetic inorganic compound composed of aluminum and nitrogen. Its crystalline structure and chemical composition grant it exceptional characteristics that are highly valued in various industrial sectors:

  • Exceptional Thermal Conductivity: AlN boasts very high thermal conductivity, often exceeding 170 W/m·K. This property allows it to efficiently dissipate heat, making it an ideal material for heat sinks, substrates, and thermal management solutions in electronic devices, LEDs, and power modules. When you buy AlN, you are investing in superior heat transfer capabilities.
  • Excellent Electrical Insulation: Alongside its thermal prowess, AlN is an outstanding electrical insulator. It possesses a high dielectric strength and volume resistivity, preventing electrical current flow. This makes it safe and reliable for use in high-voltage applications and sensitive electronic circuits. We supply AlN for applications demanding robust electrical insulation.
  • High-Temperature Stability: AlN maintains its structural integrity and mechanical properties at elevated temperatures, often up to 1700°C in vacuum and even higher in inert atmospheres. This stability is crucial for components used in high-temperature processes, such as crucibles and furnace parts.
  • Chemical Resistance: AlN exhibits good resistance to many chemicals, molten salts, and molten metals, ensuring durability and preventing contamination in aggressive environments. This makes it suitable for use in chemical processing and advanced material synthesis.
  • Low Thermal Expansion: Its coefficient of thermal expansion is relatively low and closely matches that of silicon, minimizing thermal stress in composite assemblies and enhancing device reliability.
  • Mechanical Strength: AlN possesses good mechanical strength, including high flexural and compressive strength, contributing to its durability in demanding applications.

Applications Driven by AlN Properties

The unique combination of these properties drives the demand for Aluminum Nitride in critical applications:

  • Electronic Substrates: For ICs, power transistors, and LEDs, providing thermal dissipation and electrical isolation.
  • Heat Sinks and Spreaders: To manage heat in high-power electronic devices.
  • Crucibles: For high-temperature melting and crystal growth, especially in semiconductor manufacturing.
  • Aerospace and Defense: Components requiring resistance to extreme temperatures and thermal shock.
