Abstract
A lining to support the liquid contents of an aluminium electrolytic reduction cell includes an upper layer which is penetrated by electrolyte during operation of the cell, consisting essentially of unbonded alumina, including a substantially close-packed array of alumina shapes, the gaps between the shapes being substantially filled with particulate alumina in one or more fractions having discrete particle size ranges, including a fraction having an average particle diameter not more than 20% of the average diameter of the shapes, the layer having a bulk density of at least 2.0 g/cc.
