Influence of particle size on ice nucleation and growth during the freeze-casting process
Sylvain Deville, Eric Maire, Audrey Lasalle +4
The solidification behaviour of suspensions of alumina particles during directional solidification is investigated here by in situ observations using X-ray radiography and tomograp…
Phenomenological analysis of densification mechanism during spark plasma sintering of MgAl2O4
Guillaume Bernard-Granger, Nassira Benameur, Ahmed Addad +3
Spark plasma sintering (SPS) of MgAl2O4 powder was investigated at temperatures between 1200 and 1300°C. A significant grain growth was observed during densification. The densifica…
Investigating the dispersion state of alumina suspensions: contribution of Cryo-FEGSEM characterizations
Audrey Lasalle, Christian Guizard, Sylvain Deville +2
We illustrate in this paper the interest of cryo scanning electron microscopy (cryo-FEGSEM) to investigate the stability of alumina suspensions. The stability is investigated throu…
Ice-Templating of Alumina Suspensions: Effect of Supercooling and Crystal Growth During the Initial Freezing Regime
Audrey Lasalle, Christian Guizard, Jérôme Leloup +6
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 zo…
Particles redistribution and structural defects development during ice templating
Audrey Lasalle, Christian Guizard, Eric Maire +2
The freezing of colloidal suspensions is encountered in many natural and engineering processes. It can be harnessed through a process known as ice templating, to produce porous mat…
Metastable and Unstable Cellular Solidification of Colloidal Suspensions
Sylvain Deville, Eric Maire, Guillaume Bernard-Granger +5
Colloidal particles are often seen as big atoms that can be directly observed in real space. They are therefore playing an increasingly important role as model systems to study pro…
