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.
Claims17
A layered silicate powder granule comprising flat particles, each particle comprising an evaporation-spray-dried layered silicate and a rheology modifier for modifying a crystal edge face of the layered silicate, and having an opening or recess in its surface center,
- wherein the layered silicate is at least one selected from the group consisting of smectites, swelling synthetic micas, and vermiculites.
