XTL sintyron Customized PBN ceramic Composite Heating Element

Product Instruction

The PBN-PG composite heater is a high-purity product manufactured using the Chemical Vapor Deposition (CVD) process.

It combines PBN (Pyrolytic Boron Nitride) and PG (Pyrolytic Graphite) to create a heater with excellent thermal conductivity,

corrosion resistance, and thermal shock resistance. It is designed to operate at temperatures exceeding 1500°C, making it

suitable for high-temperature applications

Characteristics

1. Thermal Performance:

   • Surface heating with excellent temperature distribution.

   • High heating rate and good thermal uniformity due to the combination of PBN's thermal conductivity and
     PG's surface heating properties.

2. Chemical Resistance:

   • Inert in corrosive gas atmospheres.

   • Resistant to acids, alkalis, and organic solvents.

3. Electrical and Mechanical Properties:

   • Not affected by magnetic fields.

   • High-purity material with minimal gas release at high temperatures.

   • Long service life and high durability.

4. Design Flexibility:

   • Available in various shapes (circular, strip-type, and square) and sizes to suit different applications.

Applications

The PBN-PG composite heater is widely used in industries requiring high-temperature and high-purity environments, including:

• Rapid Annealing Furnaces: For uniform heating in semiconductor manufacturing.

• Sputter Coating Plants: For thin-film deposition processes.

• Electron Microscopes: As heating elements in high-precision instruments.

• Molecular Beam Epitaxy (MBE): For producing Gallium Arsenide epitaxial wafers 

Advantages Over Other Materials

• Compared to Graphite Heaters: PBN-PG heaters offer longer service life, better thermal uniformity, and higher purity,
  making them ideal for semiconductor and photovoltaic applications .

• Compared to Traditional Ceramics: PBN-PG heaters provide superior thermal shock resistance and corrosion resistance,
  ensuring reliability in harsh environments
