Pyrolytisches Bornitrid Platte/Blech/Scheibe
Pyrolytic Boron Nitride Plate/Sheet/Disc is a high-purity and high-performance ceramic material. Unlike conventional hot-pressed boron nitride, it is produced through chemical vapor deposition (CVD) under vacuum conditions, using ammonia and boron halides without the need for traditional hot-press sintering or sintering agents. It offers ultra-high purity (up to 99.999%), exceptional high-temperature resistance (up to 2000℃), corrosion resistance, thermal conductivity, and electrical insulation. Advanced Keramik Hub can supply customized solutions for length, width, diameter, thickness, and surface finishes to meet specific requirements.

Pyrolytic Boron Nitride Plate/Sheet/Disc Advantages
- Non-toxic, odorless.
- High purity, exceeding 99.999%.
- Do not react with acids, alkalis, salts, or organic reagents at room temperature; slightly corrodes in molten salt or alkali solutions but is resistant to corrosion by most acids at high temperatures.
- Do not react with most molten metals, semiconductors, or their compounds.
- Exhibits good oxidation resistance below 1000°C.
- Excellent thermal shock resistance, with no cracks observed when immersed in water at 2000°C.
- High operating temperature with no sublimation point; decomposes directly into B and N above 3000°C.
- High electrical resistance and good electrical insulation properties.
- Smooth surface with no pores, does not wet most semiconductor melts.
- High flexural strength
- Easy to process with high precision
Pyrolytic Boron Nitride Plate/Sheet/Disc Applications
- High-temperature furnace linings: PBN materials can maintain stability in high-temperature environments, making them widely used as furnace linings, and internal components, such as heating elements and crucibles.
- Semiconductor manufacturing: Due to its electrical insulating properties and high-temperature stability, PBN is a key material in semiconductor production, especially for thermal insulation and electrical isolation during crystal growth processes.
- Electrical insulation materials: PBN plates and sheets are used in high-voltage environments for electrical insulation, providing protection for sensitive components in electrical devices.
- Thermal management materials: With its excellent thermal conductivity, PBN is used in applications requiring efficient heat dissipation, such as in electronic devices and laser systems for thermal management.
Pyrolytic Boron Nitride Material Properties
Pyrolytic Boron Nitride Machining
The Advanced Ceramic Hub machining center is equipped with multiple CNC lathes and CNC milling machines, and it is backed by extensive machining experience. We offer customized pyrolytic boron nitride ceramic products and profiles with extremely tight tolerances, tailored to customer requirements. During the machining process, the following precautions should be observed:
- Pyrolytic boron nitride ceramic materials can be machined using standard high-speed steel cutting tools. For harder and composite materials, carbide or diamond tools are recommended.
- Grinding operations can be performed as needed, and standard taps and dies can be used to machine threads.
- The machining process should always be kept dry, with no need for cutting oils or coolants.
- Cutting tools should be sharp and clean, and tools with negative rake angles should not be used.
- Care should be taken when clamping and securing materials to avoid applying excessive pressure. Climb milling techniques should be used to prevent edge and corner chipping.
Pyrolytic Boron Nitride Packaging
Pyrolytic Boron Nitride Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination, and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
