Carbonaceous materials for the production of aluminium - Cathode block materials - Determination of the expansion due to sodium penetration without application of pressure
This method covers the determination of linear expansion due to sodium penetration in cathode block materials used in the production of aluminium. The linear expansion of the blocks depends on the sampling direction due to anisotropy.
