Products Description
Aluminum nitride plate is a high-performance advanced ceramic plate made primarily from aluminum nitride (AlN) ceramic. As an important Group III-V compound ceramic, aluminum nitride has garnered widespread attention since the mid-20th century due to its exceptional physical and chemical properties, transitioning from laboratory research to large-scale industrial applications. The forming techniques for aluminum nitride ceramics are diverse. In addition to common methods such as tape casting, dry pressing, and isostatic pressing used to produce aluminum nitride plates, aluminum nitride ceramic plates, aluminum nitride ceramic substrates, and aluminum nitride ceramic rods, more complex-shaped aluminum nitride irregular parts, aluminum nitride structural components, and aluminum nitride parts-such as aluminum nitride turbines, aluminum nitride nozzles (including aluminum nitride top nozzles), and ceramic sleeves for fixing lasers-are widely manufactured using aluminum nitride ceramic injection (or aluminum nitride ceramic injection molding) processes.
Core Performance
- Extremely High Thermal Conductivity: This is the most prominent advantage of aluminum nitride ceramics. High-purity, advanced-process aluminum nitride plates or hot-pressed aluminum nitride ceramics can achieve thermal conductivity ranging from 170 to 230 W/(m·K), which is 5 to 10 times that of traditional alumina ceramics.
- Good Thermal Expansion Coefficient Matching Silicon: The thermal expansion coefficient of aluminum nitride closely matches that of silicon semiconductor materials.
- Excellent Electrical Insulation Properties: Aluminum nitride ceramics are good insulators, with high volume resistivity, high dielectric strength, and relatively low dielectric constant.
- Outstanding Mechanical and Physicochemical Properties: Aluminum nitride ceramics exhibit high mechanical strength and hardness, along with good wear resistance.
- Non-Toxicity: Unlike toxic beryllium oxide (BeO), aluminum nitride ceramics are environmentally friendly, safe to process and use, removing health and environmental barriers for applications in civil high-reliability fields such as ceramic sealing rings for energy storage batteries.
