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 Aln Aluminium Nitride Plates Ceramic Part Aluminum Nitride Spacer

What is aluminum nitride? Aluminum nitride (AlN) is a ceramic material made from aluminum and nitrogen. It conducts heat well, resists electricity, and handles high temperatures. People use it in electronics, machinery, and places needing heat control. Its structure stays stable even under stress or heat.

Why pick aluminum nitride plates? These plates move heat fast, keeping devices cool. They block electricity, stopping short circuits. They last longer in hot or corrosive settings compared to metals or plastics. They fit tight spaces, acting as spacers or insulators without breaking down.

Where are AlN plates used? Common uses include LED lights, power modules, and semiconductor tools. They work in laser systems, sensors, and high-frequency equipment. Factories use them for furnace parts or coating tools. Their heat control helps prevent device failures.

How to handle aluminum nitride parts? Avoid dropping or hitting them. Clean surfaces with dry cloths or alcohol. Don’t expose them to moisture before use. Store them in dry places. Use gloves to prevent oil from skin affecting performance.

How does AlN compare to alumina or beryllia? Alumina conducts heat slower than AlN. Beryllia conducts heat similarly but is toxic. Aluminum nitride is safer, non-toxic, and matches beryllia’s performance. It costs more than alumina but lasts longer in tough conditions.
