Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

5 FAQs of High Thermal Conductivity Aluminum Nitride ALN Ceramic Sheet Plate Board

What is high thermal conductivity aluminum nitride ceramic?
Aluminum nitride (AlN) ceramic is a material known for moving heat efficiently. It works better than many metals or plastics in high-temperature settings. Its thermal conductivity ranges between 170-220 W/m·K. This makes it ideal for electronics needing heat control.

Where is AlN ceramic used?
AlN ceramic sheets are common in electronics. They serve as heat sinks in LED lights, power modules, or semiconductor devices. They also work in aerospace and automotive parts where heat must spread quickly. Their electrical insulation adds safety in circuits.

Why pick AlN over alumina or aluminum?
AlN moves heat faster than alumina (20-30 W/m·K) or aluminum (200 W/m·K). Unlike aluminum, AlN doesn’t conduct electricity. This stops short circuits. AlN also resists corrosion better. It handles extreme temperatures without cracking.

Can AlN ceramic handle very high temperatures?
Yes. AlN ceramic stays stable up to 1400°C in air. In non-oxidizing environments, it lasts even longer. This makes it fit for furnaces, reactors, or engines. It won’t melt or warp under normal high-heat conditions.

How do I machine or handle AlN ceramic sheets?
AlN is hard and brittle. Cutting or drilling requires diamond tools. Avoid sudden temperature changes. These cause cracks. Clean surfaces with non-abrasive methods. Wear gloves to prevent oil stains. Store in dry areas to keep performance consistent.
