Colloid Chemical Control of Kaolinite Properties Related to Ceramic Processing
Acid-Base Interfacial Interactions Ceramic Processing Electroconductivity Interparticle Interactions Kaolinite Optimal Structures
2011/12/2
Abstract: Experimental data on structure formation in highly concentrated aqueous dispersions of kaolinite were analyzed using rheological models. The physicochemical properties of the clay mineral su...
Light Scattering Study on Sol-Gel Transformation of SiO2 Colloid at Extremely High Concentrations
Light Scattering Study SiO2 Colloids Sol-gel Transformation
2011/12/8
Abstract: Ludox SiO2 sols with a reasonably uniform size of 12 nm and in the high concentration of 10 to 40 wt% were transformed to gels by lowering the pH. The process from sol to gel, followed by li...
A Critique of Diffuse Double Layer Models Applied to Colloid and Surface Chemistry
Clay Dispersion Clay Swelling Diffuse Double Layer DLVO Electrostatic Attraction Theory Interparticle Forces Ockham's Razor Schiller Layers Smectites
2011/12/22
Abstract: The use of Derjaguin-Landau-Verwey-Overbeek (DLVO) theory in colloid science has continued to the present day in spite of the inability of this theory to explain, even qualitatively, numerou...
