Graphite Felt
Graphite is an elemental carbon (C) mineral with a hexagonal crystalline structure. This soft and flexible material is characterized by a black or grey-black color. Flexible graphite felt is available in thicknesses ranging from 5 to 20 mm, in strips up to 1400 mm wide, typically processed at temperatures exceeding 2200°C, and can be purified to less than 20 ppm of total ash.
Advantages of Graphite Felt:
Low thermal conductivity
High specific heat for quick heating and cooling of the furnace
Easy to implement, can be cut with scissors or a cutter
Not wetted by molten metals
High purity, contains very little sulfide or ash
Does not accumulate static electricity
Applications of Graphite Felt:
Thermal insulation for vacuum or inert gas furnaces
Degassing, brazing, annealing, and sintering furnaces for metals
Induction furnaces
Filters for hot or corrosive liquids and gases, and molten metals
Support for welding or brazing
