· Clay minerals are a group of minerals that are typically found in soils, sediments, and rocks. They are characterized by their small particle size, which is typically less than 2 micrometers, and their high surface area. Some of the most common clay minerals include kaolinite, smectite, illite, and chlorite.

· Abstract: Clays are irreplaceable raw materials for ceramic processing. The availability of clay deposits of suitable quality and quantity is an important competitive factor and a key issue for the economic sustainability of ceramic production. The identification of adequate sources of clay materials is an important issue that requires an

· Particle size distribution and specific surface area measurements of the samples were collected every 15 min and compared. It was observed that the increase in the surface area as a function of particle size is almost negligible (2% increase of surface area, for a D V50 reduction from 50 to 10 μm), in contrast to what is normally observed in

The clay itself may be a source of plant nutrients when it degrades. Despite these known effects it is still difficult to predict soil behaviour from clay mineralogy. This is partly because the complexities of real clays in soil have been ignored in correlative studies, and that their effects on soil bulk properties are not understood.
