Pyrolytic Boron Nitride Crucible

Pyrolytic Boron Nitride Crucible 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. It is ideal for semiconductor crystal growth, high-temperature melting, and thin film preparation.

Pyrolytic Boron Nitride VGF Crucible

The VGF crucible is a container used in the Vertical Gradient Freezing (VGF) technique for synthesizing crystals such as GaAs, InP, CZGaP, and Ge. PBN VGF crucibles can withstand high temperatures and provide a stable thermal environment, allowing the crystal to grow in a controlled manner from the bottom upwards. This results in single crystals with low defect density and high uniformity.

Pyrolytic Boron Nitride Machining

Pyrolytic Boron Nitride Machining Center HM 3

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.

Pyrolytic Boron Nitride (PBN) is a boron nitride material with ultra-high purity, typically produced through a chemical vapor deposition (CVD) process under vacuum conditions. Unlike conventional hot-pressed boron nitride, PBN does not require the addition of sintering agents or undergoes the traditional hot-press sintering process. The production process is more refined, achieving a purity of over 99.999%. Pyrolytic Boron Nitride exhibits excellent resistance to acids, alkalis, molten metals, and other chemical corrosion, along with outstanding electrical insulation properties. It is widely used in high-tech fields such as semiconductor manufacturing, high-temperature furnaces, and aerospace systems.

Hexagonal boron nitride (h-BN): Its structure is similar to graphite, often referred to as “white graphite.” The layered structure gives it excellent lubricating properties, electrical conductivity, and high-temperature stability. It is the most widely used form, primarily applied in lubricants, insulating materials, and refractory materials.

Cubic boron nitride (c-BN): Its structure resembles that of diamond, offering extremely high hardness and thermal conductivity. C-BN is mainly used in the production of cutting tools and abrasives, and is widely applied in the field of machining.

Pyrolytic Boron Nitride (PBN) is primarily produced through a chemical vapor deposition (CVD) process. In this process, precursor gases such as ammonia (NH₃) and boron trichloride (BCl₃) react under vacuum conditions, forming boron nitride films. The reaction typically occurs at high temperatures, where the gases decompose and the boron nitride deposits as a solid on the substrate surface. This production process ensures that Pyrolytic Boron Nitride materials exhibit excellent chemical stability and electrical insulation properties.
