Overview of Mirror Polished Aluminum Nitride Substrate High Smoothness Ceramic Plate

Aluminum Nitride (AlN) ceramic is an advanced technical ceramic material known for its unique combination of extremely high thermal conductivity and excellent electrical insulation properties. Unlike traditional alumina or beryllium oxide ceramics, AlN offers a thermal conductivity close to that of metals like aluminum and copper, while still acting as a robust electrical insulator. It is typically produced via powder processing and sintering, resulting in a dense, hard, and durable material ideal for demanding thermal management applications.

Features of Mirror Polished Aluminum Nitride Substrate High Smoothness Ceramic Plate

High Thermal Conductivity: Possesses a theoretical thermal conductivity of up to 320 W/m·K, with commercial grades typically ranging from 170 to 230 W/m·K, effectively dissipating heat in high-power circuits.

Excellent Electrical Insulation: Despite its metal-like heat transfer, it maintains a high volume resistivity and dielectric strength, preventing short circuits and ensuring device safety.

Low Thermal Expansion Coefficient (CTE): Its CTE closely matches that of silicon (Si) and Silicon Carbide (SiC), minimizing thermal stress and improving reliability in semiconductor packaging.

High Mechanical Strength & Corrosion Resistance: It offers good flexural strength and is resistant to attack from many molten metals and chemicals.

Non-Toxic: AlN is a safe alternative to Beryllium Oxide (BeO) ceramics, which pose serious health risks during processing and disposal.
