CFC heaters are used for high-purity silicon crystal growth, providing heat for crystal growth, with local temperatures reaching over 2200℃，as a substitute for graphite, it has a long service life and provides guarantee for the long-term growth of semiconductor and photovoltaic crystals.

The features of VET Energy’s CFC heater:

1. Compared with traditional graphite heaters, carbon/carbon heaters have better thermal shock resistance, thermal creep resistance, and thermal shock resistance;

2. Compared with traditional graphite heaters, carbon/carbon heaters have high strength, wear resistance, and long service life;

3. The resistance is not only stable, but also can be designed according to demand, which can increase the effective utilization space inside the carbon-carbon heater, and the energy consumption of a single furnace in the crystal pulling thermal field is lower.

VET Energy is specialized in high-performance carbon-carbon composite (CFC) customized components, we provide comprehensive solutions from material formulation to finished products manufacturing. With complete capabilities in carbon fiber preform preparation, chemical vapor deposition, and precision machining, our products are widely used in semiconductor, photovoltaic, and high-temperature industrial furnace applications.
