The Aluminum Nitride Ceramic Heating Disk is a disk-shaped thermal management component made from aluminum nitride (AlN) ceramic. It is designed for semiconductor equipment, vacuum heating systems, electronic packaging, and precision temperature-control assemblies. The material provides high thermal conductivity, reliable electrical insulation, and low thermal expansion, enabling fast, uniform heat transfer while maintaining dimensional and insulation stability in high-temperature and vacuum environments.
Material System
This product is made from aluminum nitride (AlN) ceramic. The material combines high thermal conductivity, reliable electrical insulation, low thermal expansion, and stable performance at elevated temperatures.
Application Scenarios
Rapid Heat Transfer
The high thermal conductivity of aluminum nitride ceramic enables heat to spread quickly across the disk surface.
Uniform Temperature Distribution
The disk-shaped structure supports more even heat spreading across the surface, helping reduce localized temperature differences when properly integrated with the heating circuit and assembly.
Reliable Electrical Insulation
The ceramic maintains electrical isolation while transferring heat, making it suitable for equipment requiring both thermal conductivity and insulation.
Dimensional Stability
Its low coefficient of thermal expansion helps the component maintain structural and dimensional stability during temperature changes.

FAQ
1. What is an Aluminum Nitride Ceramic Heating Disk?
It is a disk-shaped thermal management component made from aluminum nitride (AlN) ceramic. Depending on the design, it can serve as a heat-transfer disk, electrically insulating base, or part of an integrated ceramic heating assembly.
2. Does the heating disk include an integrated heating circuit?
The heating structure depends on the specific application design. An embedded or assembled heating circuit can be evaluated according to the required voltage, power, operating temperature, temperature uniformity, and installation method.
3. Can the AlN ceramic heating disk be used in vacuum environments?
Yes. Aluminum nitride ceramic is suitable for vacuum thermal systems, but the electrodes, bonding materials, lead wires, and mounting components must be evaluated according to the required vacuum level and operating temperature.
4. What is the maximum operating temperature?
The maximum operating temperature depends on the AlN material grade, heating structure, electrode design, bonding method, and working environment. CERAMPRO evaluates the appropriate operating range according to the application requirements.
5. Can the dimensions and machining features be customized?
Yes. Diameter, thickness, mounting holes, grooves, slots, chamfers, flatness, surface finish, and other structural features can be customized according to customer drawings.
6. How does aluminum nitride compare with alumina for heating disks?
Aluminum nitride provides higher thermal conductivity while maintaining electrical insulation and low thermal expansion. Alumina is more economical and suitable for applications with less demanding heat-transfer requirements.
7. What information is required for a quotation?
Please provide the product drawing, dimensions, tolerances, required quantity, operating temperature, voltage and power requirements, heating structure, surface finish, installation method, and application environment.
