Abstract Scope |
Controlled manipulation of motion and spatial distribution of particles in an aqueous media is of great fundamental interest in ceramic processing, potentially enabling particle assembly at different length scales for the development of novel materials and structures. While various external fields have been employed in colloidal ceramic processing, application of alternating current (AC) electric field remains limited. A significant advantage is that ceramic particles can directly respond to the applied electric field without the need for the second phase material, making the electric fields preferable for particle manipulation in aqueous media. To successfully employ AC field in ceramic processing, it is vital to gain a thorough understanding of the interactions between ceramic particles in aqueous media and field, which is currently lacking. This presentation will shed insights on these underlying interactions and the role of various variables, which include ceramic type, particle size, suspension concentration, and AC electric field parameters. |
