Carbon-carbon composite flow guides

Carbon-carbon composite flow guides are ususlly positioned above the crucible in the single-crystal growth furnaces. They collaborate with components such as heaters, crucibles, and insulation cylinders to constitute the ideal thermal field required for single crystal silicon growth.

Carbon-carbon composites use carbon as the matrix and carbon fibers and their fabrics as reinforcement, manufacturing through a combination of chemical vapor deposition (CVD) and graphitization. This precise manufacturing process offers carbon-carbon composite flow guides a dense structure and uniform composition, ensuring stable performance and meeting the requirements for continuous multi-batch use in the single-crystal silicon pulling furnaces.

This composite structure endows them with notable properties of carbon-carbon composites such as low density, high specific modulus, strong wear resistance and superior resistance to high temperatures. Relying on these superior composite outline and material properties, carbon-carbon composite flow guides are capable of directing consistent gas distribution inside the furnace throughout the single-crystal silicon development operations. Meanwhile, carbon-carbon composite flow guides are also able to shield heat to prevent heat loss and generate the necessary temperature gradient, which allows single-crystal silicon to develop under optimal thermal conditions.
