Abstract: In a tubular reactor carrying a bed of solid material into which carbon electrodes project for heating the material upon passage of a current, the outside ends of said electrodes being connected to metallic conductors in turn connected to a supply of current, the invention involves pouring lead about the end of each electrode to effect improved contact between the electrode and its respective metallic conductor. The process involving use of such electrodes to react carbon with chlorine and the oxide of silicon or metals such as vanadium, titanium or zirconium is also covered.
