A method of processing a porous article includes distributing a blended material that includes an electrically conductive material and a binder into a cavity of a mold that is at a temperature below a curing temperature of the binder. The electrically conductive material is formed from particles of the electrically conductive material that have a size distribution such that 10 vol % of the particles are less than 12 micrometers in diameter, 50 vol % of the particles are less than 27 micrometers in diameter, and 90 vol % of the particles are less than 53 micrometers. The blended material is compressed within the cavity under a molding pressure, and the mold is heated to a curing temperature of the binder to form a molded article.
