Abstract:
The invention has for its object to use an evaporation-spray drying process thereby providing layered silicate powder granules, each one containing a flat particle having an opening or recess in its surface center. Each of the layered silicate powder granule contains a flat particle including a layered silicate formed by evaporation-spray drying and a rheology modifier for modifying the crystal edge face of the layered silicate and having an opening or recess in its surface center.
