|
| As a result of this grain size, kaolinite clays have somewhat low plasticity, but they dry quickly and without problems due to their greater porosity when dry. |
|
| To get the optimum balance of technical properties and to minimize the price of the product, PBO is partially replaced with clay or kaolinite. |
|
| Illite clay behaves in a way that is midway between kaolinite and montmorillonite clays, and can be classed as the balancing point for the majority of characteristics. |
