Overview of Large Diameter Customized Aluminum Nitride Ceramic Disc

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 Large Diameter Customized Aluminum Nitride Ceramic Disc

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.

Big Diameter Customized Aluminum Nitride Ceramic Disc– Technical Specification

Material Structure

Aluminum nitride (AlN) is the major product utilized in this ceramic disc. It consists of over 99% pure AlN. Small amounts of sintering help like yttrium oxide might be added to boost thickness and thermal efficiency. The end product reveals exceptional phase pureness with very little impurities.

Dimensions and Tolerances

The disc is readily available in big sizes, generally ranging from 100 mm to 300 mm. Density can be customized between 1 mm and 20 mm, relying on application needs. All dimensions adhere to tight manufacturing resistances: size ± 0.1 mm, density ± 0.05 mm, and flatness within 10 microns per inch. Edge chamfering or beveling is optional upon demand.

Thermal and Electrical Qualities

This AlN disc provides high thermal conductivity– usually 170– 200 W/m ·K– making it perfect for warmth dissipation in power electronic devices. It additionally supplies solid electric insulation, with a volume resistivity above 10¹⁴ Ω · cm and dielectric toughness of at least 15 kV/mm. These features make certain safe and efficient procedure in high-voltage atmospheres.

Mechanical Stamina

The disc has a flexural strength of 300– 400 MPa and a Vickers firmness around 12 Grade point average. It resists fracturing under mechanical anxiety and maintains architectural stability throughout broad temperature level swings– from -50 ° Cto

800 ° C. Surface End Up and Modification

Standard surface area roughness is Ra ≤ 0.2 µm on both sides. Lapped or polished coatings are offered for optical or bonding applications. Consumers can request pierced openings, ports, metallization (such as Ti/Ni/Ag layers), or laser marking for component recognition. Each disc undergoes complete evaluation before shipment to fulfill exact specs.

Applications of Large Diameter Customized Aluminum Nitride Ceramic Disc

Applications of Huge Size Custom-made Aluminum Nitride Porcelain Discs

High-Performance Thermal Administration

Light weight aluminum nitride (AlN) ceramic discs with huge sizes are extensively used where quick and dependable warm dissipation is needed. These elements take care of high thermal loads without deforming or splitting. Their superb thermal conductivity– much more than common alumina porcelains– makes them optimal for power electronics, laser systems, and RF components. Designers select them when steady efficiency under intense heat is essential.

Advanced Semiconductor Production

In semiconductor fabrication, precision and pureness issue. Big AlN discs work as electrostatic chucks and wafer handling systems in etching and deposition devices. They resist chemical rust from hostile procedure gases. Their reduced thermal development makes certain very little dimensional adjustment during rapid home heating cycles. This security assists preserve tight resistances throughout hundreds of production runs.

Optoelectronics and Laser Solutions

High-power laser diodes and optoelectronic settings up create substantial heat in small rooms. Customized AlN discs function as substrates or warm spreaders that maintain delicate optical elements cool down. Their electric insulation avoids interference, while their smooth surface finish sustains precise optical placement. Developers count on these discs to expand device life and enhance beam quality.

Aerospace and Protection Electronic Devices

Radar, satellite interaction, and avionics systems demand products that do reliably in extreme atmospheres. Large-diameter AlN ceramic discs fulfill this need by incorporating thermal performance with mechanical toughness. They withstand resonance, thermal shock, and broad temperature swings without weakening. Armed forces and aerospace engineers specify them for mission-critical hardware where failing is not an option.

Customization for Unique Needs

Every application has different size, thickness, and tolerance requirements. Manufacturers produce AlN discs approximately 150 mm or even more in size, customized to exact client specs. Whether it’s monotony, surface area roughness, or metallization patterns, customization makes sure seamless integration right into complex systems.
