      abstract     = {Directional freeze-casting of ceramic slurries followed by
                      freeze drying and partial sintering results in materials
                      with highly anisotropic properties parallel and transverse
                      to the freezing direction. Physical measurements and optical
                      dilatometry confirm that, during sintering, freeze-cast
                      structures experience more strain along their freezing
                      direction than transverse to it. Discrete Element (DEM)
                      simulations of equivalent freeze-cast structures confirm
                      this behavior. These simulations indicate that not only is
                      sintering anisotropic on the macroscopic scale but within
                      the walls and macropores themselves. It was determined that
                      the anisotropic particle contact network that resulted from
                      the aligned macropores led to anisotropic shrinkage during
                      sintering.},
