Abstract
A porous carbon body is produced from a carbon felt with a low level of metal impurity by forming the body from a carbon felt with a low level of metal impurity, and infiltrating the body with silicon. In another aspect of the invention, an annealing furnace is treated with a halide-containing gas at elevated temperature to scavenge metal impurities. A porous carbon body is then infiltrated with silicon in the annealing furnace.
