<p>Process for the preparation of bridged clays and the bridged clays prepared by said process. The characteristic of the process of the invention is to treat thermally a reaction mixture comprising the clay in aqueous suspension, at least one salt of a cation M and a compound which supplies OH<-> ions by hydrothermal decomposition under the reaction conditions, and then to separate the product obtained. The process of the invention applies particularly well in the case of alumina bridging.</p> |
