CVD Composite Ceramics

The Ceramic Composite Heater is an advanced heating solution developed from Chemical Vapor Deposition (CVD) technology. It features a Pyrolytic Boron Nitride (PBN) insulating layer and a Pyrolytic Graphite (PG) resistive heating element. By integrating the exceptional electrical insulation of PBN with the superior electrical conductivity and thermal performance of PG, this innovative heater delivers precise temperature control, rapid thermal response, and long-term operational stability.
