Description
Product Overview
The pyrolytic graphite crucible is manufactured using chemical vapor deposition (CVD) at temperatures between 1800°C and 2000°C, creating a highly oriented crystal structure on a graphite matrix. This process yields a material with a high elastic modulus and breaking strength, especially when the deposition temperature is reduced below 1500°C. The crucible resists both extreme cold and heat, exhibits super‑diamagnetism, and offers natural lubricity, making it suitable for a wide range of industrial processes.
