Carbonaceous materials for the production of aluminium — Cathode block materials — Part 1: Determination of the expansion due to sodium penetration with application of pressure
碳质材料用于生产铝还原阴极块材料 - 第1部分:肿胀由于在压力下渗透钠测量
This document specifies a method that 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.
