Effect of particle size of calcite on the stacking order of kaolinite during mechanical grinding

open access: yesInternational Journal of Ceramic Engineering & Science, 2023
The effect of calcium carbonate (CaCO3) particles on the stacking order of kaolinite, a layered clay mineral, during the mechanical grinding process was demonstrated by grinding of expanded kaolinite without impurities (Ex‐Kaol), a methoxy‐modified ...

Effects of kaolinite layer expansion and impurities on the solid-state reaction of kaolinite

open access: yesRSC Advances, 2021
Effects of kaolinite layer expansion and impurities on the rapid formation of metastable CaAl2Si2O8 with the supression of byproduct formation were demonstrated based on the solid-state reaction of calcium carbonate with methoxy-modified kaolinite.

Kaolinite flocculation structure

open access: yesJournal of Colloid and Interface Science, 2008
Effective flocculation and dewatering of mineral processing streams containing colloidal clays has become increasingly urgent. Release of water from slurries in tailings streams and dam beds for recycle water consumption, is usually slow and incomplete.

A Comparative Study on Early‐Stage Icing Evaluation Techniques for Passive Ice Protection Systems

open access: yesAdvanced Materials Interfaces, EarlyView.
This study addresses the lack of standardized methodologies for evaluating the early‐stage icing performance of passive ice protection systems. A unified experimental protocol is proposed and applied to representative hydrophilic and hydrophobic surfaces under controlled conditions.
