Hydrous benefits

Talc and hydrous kaolins are naturally platy by nature, and degree of platiness can be enhanced by the delamination process. Oftentimes, these products are differentiated by aspect ratio which is defined as the ratio of plate diameter to plate thickness. Key benefits of shape-engineered platy particles include reduced sheet permeability along with improved smoothness and printability. 

Another benefit of crystalline metal oxides is that their high conductivities allow charge propagation along the lattice structures of thin surface layers. However, conductivity is lower in the commonly used hydrous metal oxides that are amorphous. It is possible to increase conductivity through crystallization but this significantly reduces active surface area via the removal of water and elimination of pore spacing within the material structure [79].
