The thermal behavior and decomposition of kaolinite–potassium acetate intercalation complex was investigated through a combination of thermogravimetric analysis and infrared emission spectroscopy. Thr...
Thirty seven soil samples collected from arid and semiarid regions of southern Iran were studied to determine the different forms of potassium and their relation with clay mineralogy and other soil pr...
Dynamic and controlled rate thermal analysis (CRTA) has been used to characterise alunites of formula [M(Al)3(SO4)2(OH)6] where M+ is the cations K+, Na+ or NH4 +. Thermal decomposition occurs in a se...
ABSTRACT: Design and synthesis of the agricultural and ecological superabsorbent materials with cost-efficient and fertilizer-release characteristics has recently attracted considerable interests. In ...
Abstract: KCl-, KBr-, and KI-kaolinite intercalation complexes were synthesized by gradually heating potassium-halide discs of the dimethylsulfoxide (DMSO)-kaolinite intermediate at temperatures to 33...
Abstract: Monte Carlo simulations based on tested water-water, cation-water, and water-clay potential functions were applied to calculate radial distribution functions for O-O, O-H and H-H spatial cor...

The structure of a highly disordered synthetic birnessite was studied by comparing powder X-ray diffraction (XRD) data with calculated patterns generated by BIRNDIF and WILDFIRE© in an attempt to...
Leonhardite, a partially dehydrated laumontite, and its alkali variety, primary leonhar-dite, have been studied byhigh-temperature calorimetry. The enthalpies offormation from oxides and elements at 2...
Ti-rich potassium-richterite samples weresynthesized at 900°C and 1kbar PH20and characterized by Fourier-transform infrared spectroscopy (FTIR) and Rietveld structure refinement. The infrared spectrum...
Columns for high pressure liquid chromatography were prepared from spray dried samples of montmorillonite that were heated with potassium halides (KTM) to increase both the cation density on the clay ...
