Aluminum Nitride Tube Ceramics Overview

Aluminum nitride (AlN) ceramics are special materials primarily made of aluminum nitride. They feature a unique crystal structure called wurtzite, which is formed by groups of atoms bonded together.

Key Features

Chemical Composotion:

• Aluminum (Al): 65.81%
• Nitrogen (N): 34.19%

Physical Specification:

• Density: 3.261 g/cm³
• Appearance: Usually white or off-white; clear and colorless when in single crystal form.
• Can withstand very high temperatures, up to 2450°C before breaking down.
• Thermal Expansion: Changes size slightly with temperature changes, measured at (4.0-6.0) x 10⁻⁶/°C.
• Conducts Heat Well: Has a thermal conductivity of 260 W/(m·K), which is 5-8 times better than aluminum oxide
• Max. working temperatures as high as 2200°C, making them very durable against heat and shock.
• Aluminum nitride ceramics are highly resistant to damage from molten aluminum and other hot metals. They are especially good at withstanding exposure to molten aluminum, making them ideal for use in metal processing and semiconductor applications.
