[Also in Division Cl] A crystalline rod 14 of cerium or lanthanum oxide is grown on a cathode 11 from a molten zone 15 fed with material from a consumable anode 10 of the material during passage of an electric discharge from the cathode to the anode.. The cathode may be of the same material or of carbon capped therewith. The anode may be above (as shown) or below the cathode.
