TL;DR: In this paper, the authors present silicates belonging to the halloysite and pyrosmalite groups of silicates, discussing their crystal structure and lattice parameters, magnetic properties, nuclear gamma resonance (NGR), nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) data, and optical properties.
Abstract: This document is part of Subvolume I5β ‘Phyllosilicates – Part β’ of Volume 27 ‘Magnetic properties of non-metallic inorganic compounds based on transition elements‘ of Landolt-Bornstein - Group III ‘Condensed Matter’. It presents silicates belonging to the halloysite and pyrosmalite groups of silicates, discussing their crystal structure and lattice parameters, magnetic properties, nuclear gamma resonance (NGR), nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) data, and optical properties.

TL;DR: The role of associated clay and non-clayey materials on the nature of their titration curves has been discussed in this paper and it has been observed that their influence is not very markedly manifested on these curves and hence the titration characteristics of these samples have been ascribed as due to interstratified illite-montmorillonite minerals mainly.
Abstract: pH-neutralisation curves of some natural clay samples containing interstratified illite-montmorillonite minerals have been studied. It has been observed that their titration curves are different from those of kaolinite, montmorillonite, illite and their natural mixtures. Unlike these, the titration curves of samples containing interstratified minerals show four inflections at pH ranges 5–6, 7–7.5, 8–9.5 and 10–10.5. The role of associated clay and non-clayey materials on the nature of their titration curves has been discussed. It has been observed that their influence is not very markedly manifested on these curves and hence the titration characteristics of these samples have been ascribed as due to interstratified illite-montmorillonite minerals mainly. Reasons for the polybasic character of their curves have been discussed in relation to the surface area of the samples and their crystal structure.

TL;DR: In this article, chemical classical method of analysis was carried out on them, which include: titrimetric method of determination of cation exchange capacity of the clays which showed the Abraka inland River Bed Clay with the highest capacity of 12.8 meg/100 g, and the lowest was that of Ugono-Abraka River Bed with 2.4 Meg/100.
Abstract: 1Clay samples were collected from three different areas, Abraka River bed, Abraka land river bed and Ugono-Abraka sediment. Chemical classical method of analysis was carried out on them, which include: The titrimetric method of determination of cation exchange capacity of the clays which showed the Abraka inland River Bed Clay with the highest cation exchange capacity of 12.8 meg/100 g, and lowest was that of Abraka River Bed with 2.4 Meg/100. Calcium carbonate determination was carried out using rapid titration method. The result showed that the calcium carbonate content of Abraka Inland River Bed has the highest. Finally the walkley Black method was used in the determination of percentage organic matter content of the clay and result showed that Abraka Inland Clay has the highest content of 0.28% followed by Ugono-Abraka and then Abraka River Bed Clay. And also the plasticity was determined manually and it was found out that the Ugono-Abraka Clay has a very high plasticity, that of Abraka Inland was low and that of Abraka River Bed was very low.
