ABSTRACT:
An improved filter element which can be used in gas masks is formed of short lengths of porous monolithic carbon formed by partially curing a phenolic resin to a solid, comminuting the partially cured resin, extruding the comminuted resin, sintering the extruded resin so as to produce a form-stable sintered product and carbonising and activating the form-stable sintered product.
