Semicera CFC Upper Insulation Cover is a high-performance carbon fiber composite thermal component made using resin impregnation and densification technology. It offers low density, high strength, excellent thermal stability, and uniform structure, making it widely used in semiconductor, photovoltaic, and high-temperature furnace systems.
The primary distinction between CFC hard felt insulation tubes and other CFC structural components (such as CFC crucibles, CFC flow tubes, and CFC support rings) lies in the fact that CFC hard felt insulation tubes serve as insulating materials rather than load-bearing structural components.
The CFC external deflector tube features a circular edge composed of flange edges and annular air holes. These air holes are not designed arbitrarily but are tailored to the thermal field structure, airflow control, and installation fixation requirements.
The CFC crucible, also known as a carbon/carbon composite crucible, is a high-temperature-resistant and high-strength container fabricated from carbon fiber-reinforced carbon matrix. It is primarily used in the high-temperature thermal environments for semiconductor monocrystalline and polycrystalline silicon production.
The CFC support ring, also known as a carbon fiber-reinforced carbon-based composite support ring, is a high-performance structural component fabricated using carbon fiber as the reinforcement and carbon as the matrix through carbonization and graphitization processes.
CFC carbon-carbon composite materials, boasting exceptional purity, high-temperature resistance, low thermal expansion, superior thermal conductivity, and minimal impurity precipitation, are specifically engineered for monocrystalline silicon and silicon carbide (SiC) crystal growth furnaces. They provide a comprehensive range of high-temperature thermal field components that replace traditional graphite parts, optimizing performance for advanced semiconductor and photovoltaic crystal growth processes while addressing critical challenges such as high-temperature deformation, impurity contamination, thermal field instability, and shortened service life.
