About Pyrolytic Graphite Crucible

Stanford Advanced Materials (SAM) is the leading organization in the industry to provide our clients with the best quality array of Pyrolytic Graphite Crucible. We manufacture and provide 1~200ml crucibles for whole pyrolytic graphite material and larger sizes are available for coated products.

Pyrolytic Graphite Crucibles are characterized by optimal durability, rugged design, and supreme finish.

Pyrolytic Graphite Crucibles are widely used in making jewelry and heating various elements, and components like dies and rods. Pyrolytic graphite (PG) is a synthesized material created by the chemical vapor deposition process(CVD).

Pyrolytic graphite could be used as a coating material for substrates such as normal graphite. 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.

Pyrolytic Graphite Crucible Key Features:

Extreme Temperature Resilience: Pyrolytic Graphite Crucibles are engineered to endure extreme temperatures, making them ideal for high-temperature processes such as crystal growth, sublimation, and materials vaporization.

Chemical Inertness: Pyrolytic graphite's inherent chemical inertness ensures that the crucibles do not react with the materials being processed, preserving the purity of the process and the resulting materials.

Thermal Conductivity: Pyrolytic Graphite Crucibles boast high thermal conductivity, allowing for efficient and uniform heat distribution throughout the material being processed.

Dimensional Stability: These crucibles maintain their structural integrity and dimensions even under extreme thermal stress, ensuring consistent performance throughout the high-temperature processes.

Purity and Contamination-Free: Pyrolytic Graphite Crucibles prevent contamination and impurity introduction during materials processing, critical for applications like crystal growth and vapor deposition.

Pyrolytic Graphite Crucible Applications:

Crystal Growth: Pyrolytic Graphite Crucibles are indispensable in the growth of high-purity crystals, semiconductors, and advanced materials that require precise temperature control and contamination-free environments.

Vapor Deposition: These crucibles find applications in materials vaporization processes, enabling the deposition of thin films on substrates in industries like electronics and optics.

Materials Research: Researchers use Pyrolytic Graphite Crucibles in high-temperature experiments involving the synthesis, sublimation, and analysis of advanced materials.

Semiconductor Manufacturing: The crucibles are crucial in the production of semiconductors and other electronics components that demand high purity and temperature stability.

Aerospace and Aerospace: Pyrolytic Graphite Crucibles contribute to aerospace and defense applications that involve advanced materials processing and high-temperature testing.

Pyrolytic Graphite Crucible Quality Assurance:

Our Pyrolytic Graphite Crucibles are sourced from reputable manufacturers known for their commitment to quality and innovation. Each crucible undergoes meticulous quality checks to ensure it meets the highest industry standards.
