The surface energy of palygorskite

open access: yesPowder Technology, 2007
Abstract An average value for the surface energy ( γ¯ S ) of palygorskite was determined from experimental data of spreading pressure, the surface tension of water and its contact angle using a formula based on the combination of the Young equation with a general equation of pair interaction. The value found is 226.6 mJ m − 2 .

Study of the metal ion adsorption capacity of palygorskite by computer simulation [PDF]

open access: yesJournal of the Serbian Chemical Society
Palygorskite is a magnesium-rich aluminosilicate clay mineral with a unique chain-layered structure. This structure gives palygorskite a large specific surface area and interesting physical properties.

Petroduric and 'petrosepiolitic' horizons in soils of Namaqualand, South Africa Horizontes petrodúricos y "petrosepiolíticos" en suelos de Namaqualand, Suráfrica Horizontes petrodúricos e “petrosepiolíticos” em solos de Namaqualand, África do Sul [PDF]

open access: yesSpanish Journal of Soil Science, 2012
<p>Indurated, light-coloured 'sepiocrete' horizons have been found in Namaqualand Calcisols and Durisols. These horizons resembled calcrete but were non- to only mildly calcareous, resisted slaking in acid and alkali, and often broke with
