The present application relates to aqueous slurries comprising precipitated calcium carbonates having a bimodal particle size distribution with a first maximum in particle size distribution and a second maximum in particle size distribution, as well as methods for making them and their uses.

Bimodal precipitated calcium carbonate slurries suitable for paper and board applications, methods for making the same and their uses

Compositions comprising an inorganic particulate mineral and an antimicrobial metal, methods of making said compositions, use of said compositions in a coating composition or in a polymeric article, use of said compositions to inhibit the growth of one or more microbes and use of said compositions to eliminate one or more microbes, for example from a liquid.

Inorganic particulate containing antimicrobial metal

An aqueous suspension comprising an inorganic particulate material and dimethylethanolamine, use of dimethylethanolamine to prevent pH decrease or reduce the rate of pH decrease of an aqueous suspension comprising an inorganic particulate material over time, use of dimethylethanolamine as an anti-microbial additive in an aqueous suspension comprising an inorganic particulate material, and a method of preparing an aqueous suspension comprising inorganic particulate material.

Aqueous suspension of inorganic particulate material

A pigment product suitable for use in a coating composition to provide a gloss coating on paper, the pigment product comprising a processed particulate kaolin whose particles have a particle size distribution such that at least 80% by weight of the particles have an equivalent spherical diameter less than 2 &mgr;m and not less than 8%, preferably not less than 12%, by weight of the particles have an equivalent spherical diameter less than 0.25 &mgr;m and whose particles have a shape factor of at least 45, preferably at least 50.
