Pyrolytic Boron Nitride Heater combines three layers of ultra-high purity cerámica (PBN-PG-PBN), to produce an advanced ceramic heating element system. Pyrolytic Boron Nitride (PBN) serves as the insulating substrate, while Pyrolytic Graphite (PG) acts as the conductive heating layer. It is manufactured through high-temperature chemical vapor deposition (CVD) technology. It features excellent thermal uniformity, thermal shock resistance, and chemical stability. It is capable of reaching temperatures above 1600 ℃ in minimal time. Advanced Ceramics Hub can supply customized solutions for dimension, shape, operating temperature, current, and voltage specifications to meet diverse industrial and research requirements.

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.
  • 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.

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.

Nitruro de boro hexagonal (h-BN): Su estructura es similar a la del grafito, a menudo denominado “grafito blanco”. Su estructura en capas le confiere excelentes propiedades lubricantes, conductividad eléctrica y estabilidad a altas temperaturas. Es la forma más utilizada y se aplica principalmente en lubricantes, materiales aislantes y materiales refractarios.

Nitruro de boro cúbico (c-BN): Su estructura se asemeja a la del diamante y ofrece una dureza y una conductividad térmica extremadamente altas. El C-BN se utiliza principalmente en la producción de herramientas de corte y abrasivos, y se aplica ampliamente en el campo del mecanizado.

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.
