Overview of High Purity Aluminum Nitride Ceramic Crucible Metal Evaporation Melting Crucible

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 High Purity Aluminum Nitride Ceramic Crucible Metal Evaporation Melting Crucible

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 Purity Aluminum Nitride Ceramic Crucible Metal Evaporation Melting Crucible

What makes aluminum nitride crucibles special?
High purity aluminum nitride crucibles resist extreme heat. They handle temperatures over 1800°C easily. This material also conducts heat well. Metals melt faster and more evenly inside.

Will this crucible work with my metal?
Aluminum nitride won’t react with most molten metals. It works well with aluminum, copper, silver, and gold. Avoid highly reactive metals like lithium or cesium. Check compatibility charts for your specific alloy.

How hot can I safely use this crucible?
These crucibles work reliably up to 1800°C in air. They withstand short bursts to 2000°C. Exceeding 1800°C long-term weakens the crucible. Stick to the rated temperature for best results.

How long will one crucible last?
Crucible life depends on use. Frequent high-temperature cycles shorten it. Gentle heating and cooling help. Proper handling avoids cracks. Expect many uses under normal conditions. Replace it if you see cracks or severe wear.

How do I handle these crucibles safely?
Aluminum nitride is brittle. Avoid drops or impacts. Never place a cold crucible into a hot furnace. Heat it slowly. Let it cool down slowly too. Use tongs rated for high temperatures. Wear protective gear always.
