As part of the continuous work in improving anode quality at Hydro Aluminium, several series of pilot scale anodes have been manufactured with systematic changes in coke type, recipe and green paste production. The anodes support MSc, PhD and PostDoc work in research programs supported by Hydro and the Norwegian Research Council. In addition to regular analysis; pore-, void- and grain-distribution is investigated using Micro X-Ray Computed Tomography (CT). This non-destructive 3D imaging is implemented at a cost allowing larger numbers of samples, using a methodology developed by SINTEF that yields very sharp detail, suited to interpreting micro-structural factors for relatively large volumes of 10mm to 130mm diameter. Given a better cost-to-information yield than image analysis and mercury porosimetry, Hydro will continue to support academic work with CT analysis. Examples will be shown of baked anodes before and after electrolysis testing plus crack patterns after mechanical testing.
