Pierre Jacobs, Georges Poncelet, Alain Schutz: Process for the preparation of bridged clays, clays prepared by said process, and uses for said clays. Curtis Morris & Safford, March 13, 1984: US04436832 (23 worldwide citation)

In a process for the preparation of bridged clays, a mixture of an aqueous solution of at least one metal hydroxide and aqueous clay suspension is subjected to dialysis. Said clays are suited for use as catalysts or as supports for catalysts for the conversion of paraffinic or olefinic hydrocarbons.

The colored composite material is manufactured from materials based on a hydraulic binder and dispersed reinforcing elements, for example fibrous. To obtain a colored material, a composition comprising a baked clay such as chamotte is used generally by replacing at least in part the silica in produc ...
