CVD products made from pyrolytic boron nitride and pyrolytic graphite

Our products, including boron nitride heaters, boron nitride crucibles and components made of pyrolytic graphite and pyrolitic boron nitride, are characterised by the highest quality and advanced properties. These are achieved by using the Chemical Vapour Deposition (CVD) process and offer decisive advantages in high-tech applications.

  • Optimum performance in ultra-high vacuum: crucibles made of pyrolytic boron nitride or graphite impress at extreme temperatures with minimal outgassing effects.
  • No chemical or physical impairment: Our products have no negative impact on chemical reactions or physical processes.
  • Flexibility and dimensional stability: Depending on the design, components made of pyrolytic boron nitride or pyrolytic graphite are flexible yet dimensionally stable.

Boron nitride crucible

CVT offers high-quality crucibles made of pyrolytic boron nitride in various sizes and shapes. Whether one-offs or large series - we deliver on time and at competitive prices.

  • Available variants:
  • Straight crucibles
  • Conical crucibles
  • Tubes
  • Inserts
  • Special moulds
  • Coatings

Coating technology of our products

Our coating technology combines pyrolytic boron nitride with suitable graphite materials. The result: components that combine the electrically insulating properties of PBN with the conductivity of graphite. These innovative material combinations are ideal for melting tanks, heaters and other thermally stressed components.

Boron nitride heater

The combination of pyrolytic boron nitride and pyrolytic graphite enables the production of heating elements with excellent performance. Thanks to their similar coefficient of thermal expansion (CTE), the materials can be optimally joined layer by layer.

Advantages of our boron nitride heaters (PBN-PG-PBN heaters):

  • Low mass: Ensures rapid thermal shock behaviour.
  • Chemical inertness: Resistant to many substances and environmental conditions.
  • Flexible design: Whether flat heaters or 3D heaters such as tubes - all products are customised according to customer requirements.

Components made of pyrolytic boron nitride (PBN)

Our pyrolytic boron nitride components are manufactured from PBN sheets produced in-house. We use conventional machining processes to precisely realise our customers' requirements.

Components made of pyrolytic graphite (PG)

Pyrolytic graphite is a versatile material that we produce using the CVD process. Depending on requirements, we manufacture components either from sheet material or by direct deposition on moulded parts.

Products made from pyrolytic graphite:

  • Crucibles
  • Coatings
  • Individual customised products
