C/C composite crucible holders

Carbon-carbon composites are composite materials featuring carbon fibers as the reinforcement framework and carbon as the matrix phase. The carbon fibers may exist as a continuous three-dimensional scaffold or randomly distributed short cut fibers, while the carbon matrix is typically formed through resin or pitch impregnation followed by carbonization, or via the pyrolysis and deposition of hydrocarbon gases like natural gas or propane.

This composite structure endows crbon-carbon composites with excellent high strength and rigidity, enabling them to stably support heavy objects. Their strength does not decrease but rather increases with rising temperature within a certain range. Meanwhile, C/C composite crucible holders also boasts lightweight advantages. Compared to traditional metal materials, they have a lower density and lighter weight, reducing the overall load on the equipment and greatly simplifying installation and operation procedures.

In the demanding crystal growth process, semiconductor equipment components need to be exceptionally resistant to high temperatures, and C/C composite crucible holders exactly meets such stringent requirements. Their exceptional high-temperature resistance far surpasses that of traditional metal crucibles and ceramic crucibles , enabling long-term stable use in extreme high-temperature conditions exceeding 2000℃ without affecting structural integrity. Thanks to their superior thermal shock resistance, C/C composite crucible holders are not prone to cracking or damage even in environments with rapid temperature fluctuations, making them perfectly suited for frequent thermal cycling applications.

With their excellent performance, C/C composite crucible holders are one of the core components for ensuring the stable operation of high-temperature equipments and are widely used in high-temperature metallurgical industry, chemical industry and semiconductor manufacturing field. Their performance directly affects product quality and production efficiency, making them an indispensable part of modern manufacturing.
