CB5750 PG Coated Carbon Crucible

PG Coated Carbon Crucibles Description

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

FAQ about PG Coated Carbon Crucibles

Q1: How are PG-coated carbon crucibles manufactured?

PG-coated carbon crucibles are typically produced by moulding a carbon or graphite crucible that is then coated with pyrolytic graphite through 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 employed in semiconductor fabrication due to their high thermal conductivity, chemical resistance, and their ability to withstand high temperatures. The PG non-stick coating prevents materials from adhering to the crucible, thereby preserving purity and quality.

Q3: What advantages do PG-coated carbon crucibles offer for high-temperature furnaces?

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