Freeze-casting

Freeze-casting is a specialized processing technique used to create porous materials with controlled microstructures, particularly in the fields of ceramics and biomaterials. The method involves the controlled freezing of a slurry, which typically consists of a solid powder (such as ceramic) suspended in a liquid (often water). Here’s a general overview of the process: 1. **Slurry Preparation**: A mixture of solid particles and a solvent (commonly water) is prepared.
