| 摘要 |
An anode for electrolytic oxidation of sulfur dioxide is made by coating an electrode of a graphite-like carbon material with a layer of cokable organic material such as sugar, phenolic resin, and asphalt pitch, heating the coated electrode body in an inert atmosphere to a temperature of between 400 DEG to 800 DEG C. and thereafter heating the coated electrode to a temperature in the range of 1400 DEG to 2000 DEG C., so that the material is first coked on the graphite to produce a porous flow-through electrode body which, thereafter, is heated to a higher temperature, followed by cooling. |
