Frequently Asked Questions (FAQs)

What is the difference between type 1 glassy carbon and type 2 glassy carbon?

Type 1 is a "low temperature" glassy carbon produced by heat treatment at ~ 1,000-2,000°C and consists of discreet fragments of distorted graphene layers. In general, type 1 is less compressible, more resistant to oxidation, and less permeable to gasses. Type 2 is a"high temperature" glassy carbon produced by heat treatment at ~2,500-3,000°C and consists of broken or imperfect fullerene-like nanospheroids encased in a disordered, multilayered graphene matrix. Type 2 usually contains fewer impurities and has higher electrical and thermal conductivity.
