| Abstract Scope |
Freeze casting offers a tremendous opportunity to create bio-inspired synthetic materials. The process involves the slurry preparation, solidification, sublimation and sintering to obtain controlled pore ceramics. The aim of this study is to understand the solidification process through solving the heat equation with boundary conditions in a domain that represents the experimental set up. Freefem++ was employed to understand how adjusting parameters that can be varied in the experimental setup affects the cooling patterns of the ceramic slurry. The parameters chosen were the thermal conductivity, diameter and thickness of the mould, convective coefficient and temperature at the bottom of the slurry. Results served to recognize the factors affecting the cooling patterns within the freeze casting process. Choosing an adequate setup will guarantee a directional uniform cooling pattern through the ceramic slurry. These results will help to relate the cooling patterns obtained with the final microstructure achieved in the sintered part. |
