The Effect of Glow-Discharge Plasma and Muffle Furnace Heating on the Surface Chemistry of Kaolinite

Popis výsledku v původním jazyce

Kaolinite is commonly used as a coating in the paper industry, and as a filler in the plastics industry. Therefore it is crucial that the particles are not flocculated. In order to achieve a stable system the surface chemistry is manipulated such that strong repulsive inter-particle forces are present. This paper then investigates the changes in the surface chemistry of a commercial kaolinite (SPS China Clay, Imerys Ltd, Cornwall, UK) after treatment in a muffle furnace and in a glow-discharge plasma. The effect of the surface treatment on the zeta potential of the kaolinite was investigated using electrophoretic and electroacoustic means. A ZetaPlus (Brookhaven Instruments) was used for the electrophoretic measurements and the electroacoustic measurements were made using an Acoustosizer II (Colloidal Dynamics). Furnace heating lead to a decrease in the magnitude of the zeta potential at the natural pH, and the zeta potential was always negative over the pH range 2.75 - 10. Both measur
