Pyrolytic Boron Nitride Rod
Pyrolytic Boron Nitride Rod is known for its ultra-high purity (up to 99.999%). 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. Its strong resistance to acids, alkalis, and molten metals, combined with high dielectric strength, makes it ideal for semiconductor manufacturing, high-temperature furnaces, and aerospace applications. Advanced Ceramics Hub can supply customized solutions for diameter, length, and surface finishes to meet specific requirements.
Pyrolytic Boron Nitride Rod 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.
Pyrolytic Boron Nitride Rod Applications
- Semiconductor Manufacturing: Used as high-purity support or clamping rods for crystal growth (e.g., GaAs, InP) or equipment parts, ensuring a contamination-free environment.
- Microwave and Electron Tubes: Employed as clamping or support rods in high-power microwave components (e.g., traveling wave tubes), leveraging their high dielectric strength and thermal stability.
- High-Temperature Furnace Components: Serve as core rods or support structures in vacuum or inert atmosphere furnaces, withstanding temperatures above 2000°C.
- Experimental Equipment: Act as support materials in high-temperature experimental setups, providing structural stability and corrosion resistance.Aerospace: Utilized in thermal management systems or lightweight components, benefiting from low thermal expansion and high thermal conductivity.
- Crystal Growth Assistance: Used as auxiliary supports in processes like Molecular Beam Epitaxy (MBE) or Liquid Encapsulated Czochralski (LEC), ensuring precision.
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.
