Freeze-casting, also frequently referred to as ice-templating, is a technique that exploits the highly anisotropic solidification behavior of a solvent (often, but not exclusively, water) in a well-dispersed solution or slurry to controllably template directionally porous ceramics, polymers, metals and their hybrids. By subjecting an aqueous suspension or slurry to a directional temperature gradient, ice crystals will nucleate on one side and grow along the temperature gradient.
