Kaolin is a naturally occurring mineral, consisting of hydrated aluminum silicate, and the theoretical chemical composition is 39.50% aluminum oxide, 46.54% silicon dioxide, and 13.96% water.

The kaolin deposits are located on low-relief plateaux with a lateritic cap. The kaolin strata are in the Ipixuna Formation of Upper Cretaceous Age. There are two distinct kaolin layers, a 4–5 m thick soft kaolin which is overlain in the southern portion of the basin by a 4–5 m thick hard kaolin. The soft and hard designations refer to ...

The tests showed that thixotropic properties of kaolin slurries depend upon the fluidization degree (Reeds, 1986, Pierre and Ma, 1997, Sjoberg et al., 1999). Because of it, the smallest thixotropy field loops were at lower values of the silicate modulus (Fig. 4). This relationship was best described by the quadratic function at the correlation ...

The fractal dimension values of several kaolins with different structural order and properties have been calculated from N2-adsorption isotherm data according to the Neimark method. All kaolins show a fractal regime in the same nitrogen relative pressure range, with fractal dimension values ranging between 2.38 and 2.57.

These properties include: Color: Kaolin is typically white, although its color can vary depending on the presence of impurities. The whiteness is a sought-after property for numerous applications, such as in the paper industry. Non-toxicity: It is non-toxic, which makes it safe for various applications, including in cosmetics and pharmaceuticals.
