Pyrolytic Carbon Coated Crucible
Semicorex Pyrolytic Carbon Coated Crucible is a specialized container designed to withstand extreme temperatures and harsh chemical environments.
Material Characteristics
Semicorex Pyrolytic Carbon Coated Crucibles are specialized containers designed to withstand extreme temperatures and harsh chemical environments. They are produced by depositing pyrolytic carbon with high crystalline orientation onto a graphite substrate through chemical vapor deposition (CVD) at temperatures ranging from 1800°C to 2000°C. This process occurs under controlled furnace pressure using high-purity hydrocarbon gases, resulting in a coating that imparts superior material properties to the crucible.
Exceptional Temperature Resistance of Pyrolytic Carbon Graphite
Pyrolytic Carbon Coated Crucibles are capable of withstanding temperatures up to 3000°C, making them ideal for applications involving high thermal loads. This exceptional temperature resistance is due to the pyrolytic carbon coating, which provides a thermal barrier that protects the graphite substrate from degradation. The ability of the Pyrolytic Carbon Graphite to maintain structural integrity at such elevated temperatures ensures reliable performance in the most demanding thermal environments.
High Purity and Excellent Air Tightness of Pyrolytic Carbon Graphite
The purity level of Pyrolytic Carbon Coated Crucibles exceeds 99.99%, which is critical for processes that require contamination-free environments. The coated surface is extremely pure with zero porosity, ensuring that no impurities are introduced during high-temperature operations. This high level of purity, combined with excellent air tightness, makes these Pyrolytic Carbon Graphite Crucibles suitable for sensitive applications such as semiconductor manufacturing and material synthesis.
Non-Wetting and Chemical Resistance of Pyrolytic Carbon Graphite
One of the most advantageous properties of Pyrolytic Carbon Coated Crucibles is their non-wetting surface. This means that the crucible repels and does not absorb liquids, preventing molten materials from sticking to the surface. This property facilitates easy removal of processed materials and prevents contamination, enhancing the efficiency and cleanliness of the process. Additionally, the Pyrolytic Carbon Graphite Crucibles exhibit excellent chemical resistance, making them suitable for handling corrosive substances without compromising their structural integrity.
Minimal Outgassing of Pyrolytic Carbon Graphite
Pyrolytic Carbon Coated Crucibles are ideal for use in vacuum or inert gas environments such as nitrogen or argon. Their minimal outgassing properties ensure that they do not release contaminants into the controlled atmosphere, which is crucial for maintaining the purity of the process environment. This feature of Pyrolytic Carbon Graphite is particularly important in applications where even trace amounts of outgassing can affect the outcome of the process.
