Making and examination of the rheological property of a slurry for different qualities of pottery stones based on the freeze-dry structure and the quantity of absorbed ions from raw materials and surface charge (ζ-potential) of the particles, it has become clear that there is a remarkable difference that depends on a fine distinction between the constructed minerals in the raw materials.
At present, it seems that these causes come from the absorbed ion K+ which has a close relationship to the quantity of charge, the aggregation of particles and the dispersed structure. Based on this, the practical use of Lowgrade materials can be expected from the industrial point of view.
