Anillo de nitruro de boro pirolítico
Pyrolytic Boron Nitride Ring 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, and electrical insulation. PBN ring is often used as an insulating component in high vacuum and high-temperature environments. Advanced Cerámica Hub can supply customized solutions for inner diameter, outer diameter, thickness, and surface finishes to meet specific requirements.
Pyrolytic Boron Nitride Ring 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.
- Alta resistencia a la flexión
- Easy to process with high precision
Pyrolytic Boron Nitride Ring Applications
- Fabricación de semiconductores: PBN rings can be used as insulating rings and support rings in semiconductor manufacturing.
- High-temperature Vacuum Equipment: PBN rings can function as insulators, heat shields, or structural supports in vacuum furnaces or high-temperature reactors.
- Thin Film Deposition: PBN rings can be used as substrate holders or mask components in thin film manufacturing.

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.
- Se pueden realizar operaciones de rectificado según sea necesario, y se pueden utilizar machos y terrajas estándar para mecanizar roscas.
- El proceso de mecanizado debe mantenerse siempre en seco, sin necesidad de aceites de corte ni refrigerantes.
- Las herramientas de corte deben estar afiladas y limpias, y no deben utilizarse herramientas con ángulos de desprendimiento negativos.
- Se debe tener cuidado al sujetar y asegurar los materiales para evitar aplicar una presión excesiva. Deben utilizarse técnicas de fresado de escalada para evitar el astillado de bordes y esquinas.
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.
