Pyrolytic Boron Nitride Heater Description
Pyrolytic Boron Nitride Heater combines three layers of ultra-high purity ceramics (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. Shanghai Yuepeng can provide customized solutions for dimension, shape, operating temperature, current, and voltage specifications to meet diverse industrial and research requirements.

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.
