Pyrolytic Graphite Products

Since the PG coating is made by a CVD process with high purity gas, the surface of the pyrolytic graphite-coated products has extremely high carbon purity and strength with almost zero porosity. If pyrolytic graphite material directly deposited on a mode, instead of a graphite substrate, pyrolytic graphite products without substrate could be obtained if the CVD process is long enough.

Semiconductor and related applications of molded

The process makes extensive use of molded graphite, as shown on the figure. The crucible holding the molten material is made of high-purity graphite lined with quartz, and so are the support and the heater. In some cases, the crucible is coated with pyrolytic

Graphite AAS tubes

Components are made of dense high-purity graphite coated with a well-aligned pyrolytic carbon (Pyro-C) layer: MPG-6 – fine-grained graphite characterized by high erosion resistance and strength. R4550 – fine-grained uniform isostatic graphite for complex-shaped parts with high surface quality.

High Quality Ceramic Material Supplier

It is a high purity material with no porosity which could be deposit on all kinds of graphite shapes by chemical vapor deposition (CVD). Although Pyrolytic boron nitride could be deposited on various materials, it is usually used on graphite only, since the temperature of this CVD process is extremely high and the atmosphere is corrosive.
