    摘要: A process for producing solid vermiculite products which are stable in water which comprises incorporating a source of ammonia or ammonium ions or a basic substance, preferably urea, in an aqueous suspension of vermiculite lamellae, shaping the suspension and removing water from the suspension by heating the shaped suspension at a temperature above 100.degree. C., preferably above 150.degree. C., such that ammonia or a basic substance is liberated within the suspension. The invention includes an aqueous suspension of vermiculite lamellae containing a source of ammonia or ammonium ions or a basic substance and a dry-powder mixture of vermiculite lamellae and a source of ammonia or ammonium ions or a basic substance.

    摘要: An aqueous coating composition for the corrosion-protection and/or fire-protection of substrates comprising a dispersion of chemically delaminated vermiculite lamellae in an aqueous solution or dispersion of a film-forming polymeric binder. Preferably the vermiculite lamellae are of size below 50 microns, especially below 20 microns, and the film-forming polymeric binder is in the form of a colloidal dispersion or emulsion of the polymer in water such as is commonly called a latex.
