ABSTRACT:
In order to provide enough permeability (air or liquid throughput) in a pus molded body of carbon made from a mixture of carbon powder and a binder, a first "green" body (a body of the kind that has been fired heretofore, in its green state before firing) is broken up into small pieces with the help of a jaw crusher in a manner providing coarse particles and a fraction of uniform size (largest particle diameter not more than twice the smallest) in the overall range between 0.2 and 10 mm effective diameter is used to make a second green body of molded shape by placing it in a die and applying a pressure which may be light or heavier according to the desired degree of permeability. The second green body is then coked in vacuum or in an inert atmosphere at a temperature in the range between 600.degree. to 1000.degree. C. to produce a strong body through which gas and liquid may pass with a facility far exceeding what has been accomplished before with a body of comparable strength.
