Abstract (en)
[origin: EP0531685A1] Carbonate-containing mineral fillers, pigments or similar materials are described which are characterised in that they have a) a rhombohedral or substantially circular particle shape, b) a steepness factor from 1.1 to 1.4, c) a ratio R = % of the particles < 1 <0>m DIVIDED % of the particles < 0.2 <0>m = 8 to 19 and d) a mean statistical particle diameter of 0.4 - 1.5 <0>m. <??>These materials can be used in the paper industry both as paper filler and as coating pigment. <IMAGE>
