Abstract
The electrolysis cell according to the invention is concerned with the preparation of Zr or Hf by electrolysis, from a molten mixture of alkali metal or alkaline earth chlorides and fluorides. It comprises a graphite collector which defines the anodic space and which is extended at the lower end below the level of the electrolyte by a metal wall made of metal to be deposited or coated with said metal. The wall may advantageously be made in the form of a porous diaphragm.
