Aln Aluminum Nitride Ceramic Disc

Aluminum nitride possesses various characteristics that make it suitable for a range of industrial applications: High thermal conductivity (over 170 W/mK), which is close to the values of BeO and SiC, and more than five times that of aluminum oxide (Al2O3). Thermal expansion coefficient of 4.5 × 10⁻⁶°C, similar to silicon (3.5-4 × 10⁻⁶°C). Good optical transparency. Non-toxic. Excellent electrical conductivity. The electrical properties of aluminum nitride, including its dielectric constant, dielectric loss, volume resistivity, and dielectric strength, make it an outstanding insulating material. Good mechanical properties: The mechanical strength of aluminum nitride is also a reason for its extensive use in industrial processes, offering higher bending strength compared to aluminum oxide (Al2O3) and beryllium oxide (BeO) ceramics.
