Flocculation of Illite/Kaolinite and Illite/Montmorillonite Mixtures as Affected by Sodium Adsorption Ratio and pH
Flocculation value Critical coagulation concentration Dispersion Aggregation
2012/1/4
The effect of electrolyte concentration, exchangeable sodium percentage (ESP), sodium adsorption ratio (SAR), and pH on the flocculation-dispersion behavior of 50/50 mixtures of reference illite with ...
Effect of SiO2/Al2O3 Ratio on the Thermal Reactions of Allophane. II. Infrared and X-Ray Powder Diffraction Data
Allophane Imogolite Infrared spectroscopy Silica/alumina ratio Thermal stability X-ray powder diffraction
2012/2/8
Allophanes with SiO2/Al2O3 molar ratios from 1.38 to 1.92 were heated at temperatures up to 500°C, and the changes induced were investigated by means of infrared spectroscopy (IR) and X-ray powder dif...

Allophane Dehydration Dehydroxylation DTA Silica/alumina ratio Thermal reactions
2012/2/8
Differences were found in the differential thermal analysis curves and in the temperatures of new-phase development between allophanes of high (1.91–1.99) and low (1.47–1.53) SiO2/Al2O3 ratios. The en...
Kaolinite Synthesis: The Role of the Si/Al and (Alkali)/(H +) Ratio in Hydrothermal Systems
Kaolinite Synthesis Hydrothermal Systems Ratio
2012/2/14
The Si/Al ratio of an hydrothermal system plays an important role in kaolinite synthesis. If the atomic Si/Al ratio of a system is greater than 2·0, kaolinite will disappear at 345 ± 5°C and 2 kbars w...
