Description

Glassy Carbon CAS NO 16291-96-6 is a unique, non-graphitizing form of carbon with an isotropic structure, high purity, and exceptional chemical inertness. This material is critical for applications demanding extreme resistance to corrosion, high temperatures, and electrical conductivity. It is an essential component for manufacturers and researchers in the electrochemical, semiconductor, and high-temperature furnace industries.

Application

• Electrochemical Electrodes: Used as working electrodes in voltammetry, biosensors, and fuel cells due to its wide potential window and low background current.
• High-Temperature Crucibles & Boats: Ideal for melting and processing high-purity metals, semiconductors, and glasses in inert or vacuum atmospheres.
• Corrosion-Resistant Components: Employed in pumps, seals, and valves for handling aggressive chemicals like strong acids and alkalis.
• Semiconductor Processing: Used as susceptors, heaters, and wafer carriers in chemical vapor deposition (CVD) and molecular beam epitaxy (MBE) systems.
• Laboratory & Research Tools: Fabricated into discs, plates, and rods for use in spectroscopy sample holders and other precision labware.
• Medical Implants & Devices: Investigated for use in long-term implantable devices due to its biocompatibility and biostability.
