BN5749 PG Coated PBN Crucible

PG-Coated PBN Crucible Description

PG-coated PBN crucibles combine the excellent thermal and chemical properties of pyrolytic boron nitride with the high thermal conductivity and non-stick properties of pyrolytic graphite. This combination renders them suitable for ultra-pure high-temperature applications in semiconductor manufacturing, materials research, metal processing, and optoelectronics. Their durability, purity, and performance under extreme conditions make them indispensable in advanced technological and scientific processes.

Frequently Asked Questions about PG-Coated PBN Crucibles

Q1: How are PG-coated PBN crucibles manufactured?

PG-coated PBN crucibles are typically produced through Chemical Vapour Deposition (CVD). The PBN crucible is first shaped and then coated with a PG layer, resulting in a uniform and durable coating.

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

PG-coated PBN crucibles are employed due to their high purity, thermal stability, and chemical resistance. They can withstand high temperatures and corrosive environments present during processes such as crystal growth and epitaxy.

Q3: Can PG-coated PBN crucibles be customised for specific applications?

Yes, PG-coated PBN crucibles can be manufactured in various shapes and sizes to meet specific application requirements and ensure optimal performance.
