XTL sintyron  High Purity 99.99% Pyrolytic Boron Nitride substrate PBN 
Heating element Heater

Product Instruction

PBN-PG composite heater is manufactured using the Chemical Vapor Deposition (CVD) process, which ensures high purity
and excellent performance. The substrate consists of a layered structure, typically PBN-PG-PBN, where PBN acts as an
insulating layer and PG serves as the resistive heating element. This combination provides superior thermal conductivity,
thermal shock resistance, and chemical inertness, making it ideal for high-temperature applications 

Characteristics of PBN Substrate

1. Thermal Properties:

   • High thermal conductivity and excellent temperature uniformity due to the surface heating properties of
     PG and the thermal conductivity of PBN.

   • Operates at temperatures exceeding 1500°C, with some designs capable of reaching 1600°C.

   • Low thermal mass and fast thermal response, enabling precise temperature control.

2. Mechanical Properties:

   • High mechanical durability and dimensional stability, even under extreme thermal gradients .

   • Excellent thermal shock resistance, allowing rapid heating and cooling without damage.

3. Chemical Properties:

   • Chemically inert to most metals, acids, alkalis, and organic solvents, making it suitable for corrosive
     environments.

   • Minimal gas release at high temperatures, ensuring high-purity conditions for sensitive processes.

4. Electrical Properties:

   • PBN provides electrical insulation, while PG acts as the resistive heating element, enabling efficient
     and safe operation.

Applications of PBN Composite Heater Substrate

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

1. Semiconductor Manufacturing:

   • Rapid annealing furnaces for wafer processing.

   • Molecular Beam Epitaxy (MBE) for producing Gallium Arsenide epitaxial wafers.

   • Sputter coating and metal evaporation processes.

2. Research and Analysis:

   • Heating elements in electron microscopes for sample analysis.

   • Superconductor substrate heating.

3. Advanced Materials Processing:

   • MOCVD (Metal-Organic Chemical Vapor Deposition) heaters.

   • High-temperature furnaces for crystal growth and material synthesis 

Advantages Over Other Materials

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

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