Abstract

Carbon ptd. esp for use as electrode in the prodn of aluminium, is baked by heating the pdt to 900-1400 degrees C so that the surface of the pdt. reaches a temp of is not >700 degrees C before the centre of the pdt. reaches a temp of 450 degrees C, the temp of the centre of the pdt first being brought to 120-170 degrees C and then to >450 degrees C in 10 hrs. Method avoids cracks and breakages in the baked carbon ptd. and total baking time is considerably decreased.
