  • Bidirectional freeze casting for fabricating lamellar structures
    Patent number: 10293521
    Abstract: This disclosure provides systems, methods, and apparatus related to freeze casting. In one aspect, a method comprises providing an apparatus. The apparatus comprises a container and a cooling surface. A bottom of the container comprises a wedge. The wedge comprises a first substantially planar surface and a second substantially planar surface with an angle between the first and the second substantially planar surfaces. An interior bottom of the container comprises the second substantially planar surface. The cooling surface is in contact with the first substantially planar surface. A slurry is deposited on the second substantially planar surface, the slurry comprising a plurality of particles in a liquid. The cooling surface is cooled to cool the slurry at a specified cooling rate.
    Type: Grant
