| Abstract Scope |
Ice-templating technique enables the fabrication of directionally porous ceramic materials. In recent years, extrinsic manipulation of ice-templated structure using energized fields has received significant attention. However, the potential of electric fields is yet to be fully explored for the ice-templating technique. 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. Also, electric fields can be applied to different concentration of aqueous ceramic suspensions. In this presentation we will discuss our ongoing efforts in using electric fields in the manipulation of ceramic particles in aqueous media and fabrication of ice-templated ceramics. We will discuss the role of various parameters of electric field in the manipulation of ceramic particles and ice-templated microstructure. Preliminary results on computational modeling of the interactions between ceramic particles and electric field will be also presented. |
