Abstract
A process is described for creating the flow properties to filtration residues from sodium production. These viscous-to-hard filter residues can be changed into a thin-fluid consistency by intensively agitating them under an inert gas for 2-6 hours at temperatures between 300.degree. and 600.degree. C.
