Overview of High Purity Aluminum Nitride for Ceramic Substrate Production

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 High Purity Aluminum Nitride for Ceramic Substrate Production

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.

High Pureness Aluminum Nitride for Ceramic Substrate Manufacturing

Product Review

High pureness light weight aluminum nitride (AlN) is an essential raw material used to make advanced ceramic substrates. These substratums are necessary in electronics that need strong warmth dissipation and electric insulation. Our AlN powder satisfies strict market standards for performance and dependability.

Purity and Structure

The item contains at least 99.9% aluminum nitride. Contaminations such as oxygen, carbon, and metals are kept to extremely low degrees. Oxygen web content remains below 0.45 wt%, while total metallic impurities stay under 300 ppm. This high degree of pureness makes certain consistent thermal conductivity and mechanical toughness in the final ceramic parts.

Particle Qualities

Our AlN powder includes a controlled fragment dimension circulation. The ordinary particle dimension (D50) varies from 1.0 to 2.5 micrometers, depending on consumer needs. Bits are round or near-spherical, which helps improve packing density throughout forming. Low load lessens issues in eco-friendly bodies and sintered components.

Trick Efficiency Benefits

Ceramic substratums made from this AlN offer excellent thermal conductivity— generally over 170 W/m · K after sintering. They likewise reveal high electric resistivity and reduced dielectric loss, making them perfect for power components, LED packages, and RF tools. The product preserves stability at high temperatures and stands up to thermal shock.

Quality Assurance

Every batch undertakes strenuous screening making use of XRF, ICP-MS, laser diffraction, and BET area analysis. We adhere to ISO 9001-certified production procedures to ensure batch-to-batch uniformity. Packaging is carried out in moisture-resistant containers under dry nitrogen to avoid hydrolysis and maintain powder top quality during storage and transport.

5 FAQs of High Purity Aluminum Nitride for Ceramic Substrate Production

Frequently Asked Questions: High Purity Aluminum Nitride for Ceramic Substrate Production

What is high purity aluminum nitride used for?

High purity aluminum nitride (AlN) is mainly used to make ceramic substrates. These substrates are key parts in electronics that need strong heat control. You will find them in LED lighting, power modules, and high-frequency devices.

Why does purity matter in aluminum nitride?

Purity directly affects how well the material moves heat. Higher purity means better thermal conductivity. Even small amounts of impurities like oxygen or metals can lower performance. For reliable results in demanding applications, purity above 99.5% is often required.

How does aluminum nitride compare to other ceramic materials?

Aluminum nitride stands out because it conducts heat very well while still acting as an electrical insulator. It performs better than alumina (Al₂O₃) in heat management. It also matches silicon closely in thermal expansion, which helps prevent cracks during heating and cooling cycles.

What particle size is best for substrate production?

Fine and evenly sized particles work best. A typical range is 0.5 to 2 micrometers. This helps create dense, uniform green bodies during pressing. Consistent particle size also supports smooth sintering and reduces defects in the final product.

How should high purity aluminum nitride be stored?

Store it in a dry, sealed container away from moisture. Aluminum nitride can react with water and form ammonia gas. Keep it in a cool place with low humidity. Always handle it in controlled environments to avoid contamination and maintain quality.
