    摘要： The invention consists in the use, in a process of manufacture of GCC and PCC co-ground in water, of a co-grinding agent characterised in that: a) it is constituted by a least one homopolymer and/or at least one copolymer of acrylic acid, which is partially neutralised, of which the rate of molar neutralisation is less than 75% of the total acid functions, b) and in that it is introduced: during the stage of preparation of the aqueous suspensions of GCC and PCC, and/or during stage 2) of co-grinding, and possibly during the stage of co-grinding and another stage of concentration, and possibly during this other stage of concentration. The invention also lies in the resulting aqueous suspensions of GCC and PCC, in the dry pigments of GCC and PCC obtained, and in the use of these products in paper, paint, rubber and plastic.

    摘要： The invention discloses a method for preparing particles comprising a dense silica shell and a core of another material, through rapid precipitation of active silica from a an aqueous alkaline metal silicate solution with pH adjustment by means of an acidifying agent, on a material support other than silica, separation of the silica slurry formed and drying of the recovered silica suspension. These composite particles consisting of a shell formed of dense silica and a non-polymer organic material core with biological, in particular phytosanitary, activity can be used for the slow release of the said solid non-polymer organic material with biological, in particular phytosanitary, activity, by slow diffusion through the silica shell.

    摘要： MIXTURES OF ALKALINE EARTH CARBONATES AND METAL OXIDES, TOGETHER WITH DISPERSANTS AND BINDER ADDITIVES ARE DRIED TO PROVIDE PRODUCTS PARTICULARLY SUITABLE FOR BULK HANDLING, STORAGE AND SHIPMENT. THE PRODUCT CAN BE PREPARED IN SUCH MANNER AS TO HAVE EXCELLENT DRY-FLOW CHARACTERISTICS, GOOD PELLICLE STRENGTH AND MODERATELY HIGH BULK DENSITY, WHILE RETAINING THE SMALL PARTICLE SIZE OF THE INDIVIDUAL CRYSTALLITIES OF WHICH THE DRIED PELLICLES ARE FOMED. THE PRODUCTS MAY BE PARTUCULARLY DAPTED FOR USE IN CERAMIC INDUSTRIES AND/OR MAY BE ADAPTED FOR USE IN AQUEOUS SUSPENSIONS, IN WHICH CASES THEY ARE PROVIDED WITH READY DISPERSIBILITY AND HIGH REACTIVITY.
