Pyrolytic Boron Nitride Rod Description
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. Shanghai Yuepeng can supply customized solutions for various diameters, lengths, 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; it 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
- High-Temperature Insulating Parts: PBN rods are used as insulating components in high-temperature furnaces and reactors due to their excellent electrical insulation and thermal stability.
- Semiconductor Processing: They serve as precision parts in semiconductor equipment, ensuring contamination-free environments during wafer processing and crystal growth.
- Vacuum Technology: PBN rods are used in vacuum chambers and UHV systems, where their low outgassing properties maintain purity and system integrity.
- Chemical Handling Tools: PBN rods are used to manipulate or support molten metals and corrosive chemicals, benefiting from their strong chemical inertness.
- Research and Laboratory Equipment: In scientific research, PBN rods are utilized as structural, insulating, or support elements under extreme heat and chemically aggressive conditions.

Pyrolytic Boron Nitride Material Properties
Pyrolytic Boron Nitride Machining
Shanghai Yuepeng 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 carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
