Pyrolytic Boron Nitride Custom Parts Description

Pyrolytic Boron Nitride Custom Parts are high-purity, high-performance ceramic components manufactured through chemical vapor deposition (CVD). They offer ultra-high purity (up to 99.999%), exceptional high-temperature resistance (up to 2000℃), and excellent chemical stability. Their low thermal expansion coefficient and thermal shock resistance ensure structural integrity under extreme conditions. Shanghai Yuepeng can provide customized solutions for diverse industrial and research requirements, from intricately shaped crucibles and boats to precision insulators and substrates.

Pyrolytic Boron Nitride Custom Parts 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.
  • High flexural strength
  • Easy to process with high precision

Pyrolytic Boron Nitride Custom Parts Applications

  • Semiconductor Industry: Used in MOCVD, PVD, and CVD equipment as crucibles, boats, and liners for epitaxial growth and thin-film processing due to their high purity and thermal stability.
  • Aerospace Engineering: Serves as heat-resistant and lightweight structural components in propulsion systems and thermal protection units.
  • High-Temperature Furnaces: Applied as custom-shaped insulators, shielding parts, and containers that withstand extreme heat without contamination.
  • Optoelectronics: Provides stable environments for crystal growth and laser device manufacturing, where purity and non-reactivity are critical.
  • Vacuum and Plasma Systems: Function as insulating and protective components in plasma chambers and vacuum equipment thanks to their chemical inertness and low outgassing.

Pyrolytic Boron Nitride Machining

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.
