The surface of a water-insoluble inorganic material (metal carbonate and/or sulphate) is brought into contact, in the presence of water, with a precipitated insoluble metal silicate, the silicate at the surface of the inorganic material is dried and is treated with a bonding organosilane. The products obtained can be used as filler for the reinforcement or pigmentation of synthetic polymer composites to which these products impart better mechanical characteristics. |
