Carbonaceous materials for the production of aluminium - Cathode block materials - Part 1: Determination of the expansion due to sodium penetration with application of pressure
This method covers the determination of linear expansion under external pressure 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.
