Carbon articles are made from stacked or wound layers of (primarily) cellulose which are impregnated with thermosetting resin, cured under pressure to flat or curved sheets, and heated to >800 degrees C in a non-oxidising atmos. The laminated material used is specifically phenolic or cresol resin-impregnated cotton fabric. Process produces thick-walled articles if required, having micro-porosity and without blistering, it uses common raw material, prods. are suitable for e.g. crucibles, conductors, temp.-resistant thermal insulation, filters, prostheses, electrodes because of their chemical and thermal resistance etc. |
