Abstract
The invention relates to a process for the production of a layered double hydroxide comprising carbonate by preparing a divalent and trivalent metal ion source-containing slurry, which is subsequently treated solvothermally. If the slurry does not contain a divalent metal ion source containing carbonate, a carbonate source is added during or after the solvothermal treatment.
