Crystal tilt and replica of the crystal morphology in ice-templated structures DevilleSylvain 2016 Schematic representation of a dendritic ice crystal growing in a temperature gradient, and micrographs showing the replica of the crystal morphology in ice-templated structures. The replica of the dendritic crystals (when grown in a particle suspension) has numerous dendritic surface features. This phenomenon is encountered in materials processing routes called ice-templating or freeze-casting.
