CB5750 Pyrolytic Graphite (PG) Coated Carbon (C) Crucible

PG Coated Carbon Crucible Description

PG Coated Carbon Crucible combines the excellent thermal conductivity and mechanical strength of graphite with the high purity and chemical resistance of pyrolytic graphite. This combination makes them ideal for high-temperature and high-purity applications in semiconductor manufacturing, metal processing, high-temperature furnaces, and chemical processing. The PG coating enhances the crucible's performance by providing a non-stick surface, improving chemical resistance, and maintaining the purity of processed materials, making these crucibles indispensable in advanced technological and industrial applications.

PG Coated Carbon Crucible FAQs

Q1: How are PG coated carbon crucibles manufactured?

PG coated carbon crucibles are typically produced by forming a carbon or graphite crucible, which is then coated with pyrolytic graphite using chemical vapour deposition (CVD). This process ensures a uniform and durable PG layer.

Q2: Why are PG coated carbon crucibles used in semiconductor manufacturing?

These crucibles are used in semiconductor manufacturing due to their high thermal conductivity, chemical resistance, and ability to withstand high temperatures. The non-stick PG coating ensures that materials do not adhere to the crucible, maintaining purity and quality.

Q3: How do PG coated carbon crucibles benefit high-temperature furnaces?

In high-temperature furnaces, PG coated carbon crucibles provide efficient heat distribution and resistance to thermal shock and chemical corrosion, ensuring reliable and consistent performance.
