In this work, a study on structural, dielectric and surface morphological properties of ball clay with wet grinding is undertaken. The wet grinding treatment was performed using ball and vibro mills for different time spells of 2, 4, 8 and 16 h. The raw material and ground ball clay samples were subjected to the XRD, LCR meter and SEM to investigate the structural, dielectric and morphological properties respectively. The compositional analysis of the raw material was also carried out using energy dispersive spectroscopy (EDS). The XRD patterns reveal that the kaolinite is the main clay mineral along with quartz and the samples become amorphous in nature with grinding treatment. The dielectric constant and dissipation factors are also calculated with frequency and temperature. The ground sample for 8 h shows maximum dielectric constant and dissipation factor at 100 kHz and 1 MHz frequencies respectively while ground sample for 16 h shows maximum dielectric constant at 1 MHz. An increase in dielectric constant at the high frequency range ( MHz) is observed with grinding treatment. The SEM studies reveal that the grains are densely packed, well defined and having continuous solid phase. The grain size is observed to be reduced with wet grinding due to increase in surface area.
