Application of graphite felt

Graphite felt is a perfect material for high temperature insulation composites for vacuum furnaces hot zones

Cylinder heat shielding

Heat shielding board

Heat shielding board

Heat shielding board

Another application of graphite felt is making a fibrous electrodes (3D electrodes) with high surface area

↑ Graphite felt is used for gold extraction (electo chemical process)

↑ ↓  Graphite felt is used as an electrode for microbial fuel cells

Graphite felt is a very good electrically conductive matrix for microbial activity in microbial fuel cells
