Description

Glassy Carbon CAS NO 68647-86-9 is a unique, non-graphitizing form of carbon characterized by its high purity, isotropic structure, and glass-like fracture. This material matters for its exceptional combination of properties, including high temperature resistance, excellent chemical inertness, and superior electrical conductivity. It is essential for industries requiring robust, corrosion-resistant, and conductive components, such as advanced electrochemical systems, high-temperature furnace fixtures, and semiconductor manufacturing.

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 & Furnace Parts: Ideal for melting metals and handling corrosive materials at extreme temperatures thanks to its thermal stability and resistance to thermal shock.
• Semiconductor Processing Equipment: Employed in wafer carriers, susceptors, and other components where purity and chemical resistance are critical.
• Analytical Chemistry: Serves as a substrate or component in specialized labware and spectroscopic sample holders.
• Medical Implants & Devices: Utilized in specific biomedical applications where biocompatibility and durability are required.
• Corrosion-Resistant Coatings: Applied as a protective layer on substrates exposed to harsh chemical environments.
