15μm Single-Crystal Aluminum Nitride (AlN) Powder - High Thermal Conductivity Insulating Filler

Aluminum Nitride (AlN) thermal filler is a high-performance ceramic material widely used in thermal management applications due to its exceptional properties. Here’s a detailed breakdown of its functional roles: 1. Heat Dissipation (Primary Function) High Thermal Conductivity (~170-200 W/mK) – Efficiently transfers heat away from hotspots in electronic components (e.g., CPUs, power modules, LEDs), making AlN powder ideal for high thermal conductivity fillers. Reduces Thermal Resistance – Improves heat flow in composites (e.g., thermal interface materials (TIMs), epoxy resins), enhancing performance in electronic cooling solutions. 2. Electrical Insulation Dielectric Strength (>15 kV/mm) – Prevents electrical short circuits while conducting heat, critical for high-voltage applications (e.g., power electronics, EV batteries), where AlN ceramic filler ensures reliability. 3. Thermal Expansion Matching CTE (Coefficient of Thermal Expansion) ~4.5 ppm/K – Closely matches silicon and semiconductors, minimizing stress in bonded interfaces (e.g., chip packaging), making AlN single crystal filler a preferred choice for semiconductor thermal management. By incorporating ultra-pure AlN filler or nanoscale AlN powder, manufacturers can optimize thermal conductivity while maintaining electrical insulation, making it a top choice for advanced thermal management ceramic materials.
