Abstract
A process for prepn. of porous C plates is claimed comprising: (a) forming a sheet from a mixt. of 65-90 (pref. 75-90) pts. wt. C fibre-forming organic fibre and 10-35 (pref. 10-25) pts. wt. pulp according to a paper making method; (b) impregnating this sheet with a soln. of an orgnaic polymer, pref. in an amt. of 20-200 wt.% polymer, based on wt. of sheet; (c) oxidising this impregnated sheet, pref. at a temp. of 150-350 deg. carbonising and (d) C in air this infusibilised sheet a a temp. of at least 800 deg. C in an inert gas atmos. Opt. the sheet can also incorporate a strengthening agent. Opt. the impregnated sheet, or opt. a number of sheets laminated together, are heat-pressed to effect moulding and curing and then oxidised. This heat pressing is pref. carried out at a temp. of 150-220 deg. C for 1-60 min.
