Prekės aprašymas

The carbon-carbon composite crucibles primarily stabilize crucible in the hot zone system of crystal pulling furnaces. This effectively ensures smooth silicon ingot production under high-temperature pulling conditions. Boasting exceptional performance that significantly enhances silicon ingot quality and production efficiency, it is widely used in the semiconductor and photovoltaic industries.

Semicorex carbon-carbon composite crucibles are refined from high-performance carbon fiber preforms via a combination of chemical vapor deposition (CVD) and graphitization. This precise manufacturing process yields crucibles with a dense structure and uniform composition, ensuring stable performance that meets the demands of continuous multi-batch use in crystal pulling furnaces.
