Carbon-Carbon Composite Heaters & Heating Elements
Discover lightweight, long-life carbon-carbon composite heating elements from BZNCarbon. Designed for high-temperature furnaces including polycrystalline silicon and vacuum systems.
Description
BZNCarbon’s carbon-carbon composite heaters and heating elements are engineered for high-efficiency thermal applications, including polycrystalline silicon furnaces and other advanced processing equipment. These components are crafted from 2D, 2.5D, or 3D carbon composite structures and deliver unmatched stability, long operational life, and exceptional resistance to thermal shock.
With bulk densities ranging from 1.4 to 1.8 g/cm³, we customize every part based on customer drawings and operational demands, using precision machining and high-temperature processing (>2200°C) to ensure reliable, reproducible performance.
What Are Carbon Composite Heaters?
Carbon-carbon composite heaters are formed by reinforcing carbon fibers in 2D or multidirectional patterns, then densifying the structure through graphitization. This creates lightweight components that maintain their shape and electrical/thermal performance even under extreme temperatures.
Due to the nature of carbon-carbon materials, these heaters exhibit low thermal expansion, fast heating response, and excellent oxidation resistance in protected atmospheres.
Common Applications
Polycrystalline Silicon Production Furnaces
Vacuum and Sintering Furnaces
High-Temperature Reactors
Crystal Growth Chambers (Czochralski & Bridgman)
Semiconductor Wafer Processing Equipment
Solar Cell Manufacturing Lines
Laboratory Thermal Equipment and R&D Furnaces
