The materials were characterized using X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscope (FESEM), and vibrating sample magnetometer (VSM).
Explain in detail:-4.5 M then kaolinite is stable, - gibbsite is unstable; that is, it will not form or if it has been there, it will react with Si(OH)4 to form kaolinite. c.) Acid saturation and dissolution of montmorillonite If montmorillonite (or smectite, in general) is saturated with H+, it will self decompose.
Explain in detail:release by the clay minerals kaolinite, montmorillonite, and illite. Soil Sci. Soc. Am. J. 50:1442-1448. BORON is AN ESSENTIAL ELEMENT in plant nutrition being required in low concentrations for suffi-ciency and producing toxicity symptoms and marked yield decrement at higher concentrations. Since the concentration range between deficiency and ...

Explain in detail:Abstract: Cation charges present on the surfaces of clay minerals are expected to play a major role in industrial processes involving dry electrostatic separation of granular mixtures containing clay particles. A recent promising potential application has been the removal of clay from British Columbia pulverized coals prior to burning. The clay minerals kaolinite and montmorillonite form the ...
