We investigate the ice-templating behaviour of alumina suspensions by in-situ X-rays radiography and tomography. We focus here on the formation and structure of the transitional zone, which takes place during the initials instants of freezing. For many applications, this part is undesirable since the resulting porosity is heterogeneous, in size, morphology and orientation. We investigate the influence of the composition of alumina suspensions on the formation of the transitional zone. Alumina… Expand
Unidirectional freezing of ceramic suspensions: in situ X-ray investigation of the effects of additives.
Using in situ X-ray radiography, unidirectional freezing of titanium dioxide suspensions is investigated and it is demonstrated that because each regime corresponds to a given final structure understanding the particle motion and redistribution at the ice-front level was essential. Expand

Interfacial undercooling in solidification of colloidal suspensions: analyses with quantitative measurements
It is shown that the interfacial undercooling primarily comes from SCS caused by the additives in the solvent, while PCS is minor, which implies that the thermodynamic effect of particles from thePCS is not the fundamental physical mechanism for pattern formation of cellular growth and lamellar structure in the solidification of colloidal suspensions, a general case of ice-templating method.
