Materials for the production of primary aluminium. Dense refractory bricks. Determination of cryolite resistance PAS 015 The method described in BS1 Scope This International Standard covers materials for the production of primary aluminium. This International Standard specifies a method for the determination of the resistance of dense refractory bricks to cryolite melt with excess sodium fluoride.
