When the clay is worked by a technique such as pugging which requires the use of very high clay solids, supplementary dry kaolin must be incorporated with the fluidized cake to bring the solids to a suitable level. If necessary, the mixture of colloidal clay, kaolin, dispersant and Water is adjusted by the addition of water to a kaolin content ...
Natural kaolin was refluxed with sulphuric acid of different concentrations 1 M, 3 M, 5 M and 10 M at 110 °C for 4 h followed by calcination at 500 °C for 2 h.The physico-chemical characteristics of acid-leached kaolinite clay were studied by XRF, XRD, FTIR, TGA, DTA, SEM and N 2 adsorption techniques. XRF and FTIR studies indicate …
A high solids structured kaolin clay slurry having improved high shear rheology is manufactured by a process which comprises the sequential steps of forming an aqueous composition by mixing water and a lithium-based dispersant and then mixing structured kaolin clay particles with the aqueous composition to form the desired high solids slurry.
Water Absorption levels of popular clays: (Kaolinite) Kaolin Clay: 65%. (Illite) French Green Clay: 150-200%. Bentonite Clay: 300 – 700%. The higher the absorption level, the more moisture the clay takes out of your skin. Bentonite clay can absorb 300-700% of its mass in water, while Kaolin clay absorbs only 65%.

Kaolin is a plastic raw material, particularly consisting of the clay mineral kaolinite. The chemical formula is Al2O3.2SiO2.2H2O (39.5% Al2O3, 46.5% SiO2, 14.0% H2O). In systemic mineralogy, kaolinite ranks among phyllosilicates, which are stratified clay minerals formed by a net of tetrahedral and octahedral layers.
