The absorption of sodium vapour in commercial cathode materials for aluminium electrolysis has been studied within the range 1020–1227 K and 3–600 Torr. The absorption increases strongly with decreasing degree of graphitization. The absorption of sodium in the commercial materials can be described as a BET isotherm with calculated surface area between 9 and 124 m 2 /g. The measured surface...
A number of different products are formed in the synthesis of fullerenes using the DC carbon arc evaporation of graphite. Fullerenes are found in the soot that condenses from the vapour phase, while nanotubes are located in the material that deposits on the cathode. This paper reports the discovery of a deposit on the anode, which is similar in appearance and composition to that formed on the cathode;...
