Overview of Aluminum Nitride Ceramic Crucible and Aluminum Nitride Aln Ceramic Boat

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 Ceramic Crucible and Aluminum Nitride Aln Ceramic Boat

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 Aluminum Nitride Ceramic Crucible and Aluminum Nitride Aln Ceramic Boat

What’s Aluminum Nitride ceramic good for?
Aluminum Nitride ceramic handles extreme heat well. It resists chemical corrosion too. Crucibles and boats made from it work great for high-purity metal melting, crystal growth, and semiconductor processing. It won’t easily crack under sudden temperature changes either.

How hot can AlN crucibles and boats get?
They work reliably long-term up to about 1800°C (3272°F) in inert atmospheres like nitrogen or argon. Short bursts might reach higher, maybe 2200°C (3992°F), but check the specific product details first. Going too high damages them.

Can I use AlN with reactive metals?
Be careful. Aluminum Nitride resists molten salts and many metals. But avoid molten aluminum, lithium, or alkaline earth metals like calcium. These can react with the AlN surface, causing damage. Stick to inert gases or vacuum for best results.

How do I clean AlN crucibles and boats?
Clean them gently after cooling. Use warm water and mild detergent first. For stubborn residues, try dilute acids like nitric or hydrochloric acid. Avoid abrasive scrubbing. Never use strong alkalis like hot sodium hydroxide. Those etch the surface.

What’s the difference between a crucible and a boat?
Shape matters. Crucibles are deep cups for holding and melting materials. Boats are shallow, open trays. They’re ideal for transporting samples inside furnaces or for thin film coating processes. Both are made the same way, sintered at high temperatures. Choose based on your specific task.
