POROUS ARTICLES, METHODS, AND APPARATUSES FOR FORMING SAME

摘要

A mold for forming a ceramic article can include a first material having a first thermal conductivity and a second material having a second thermal conductivity different from the first thermal conductivity. The first material may be at least partially embedded within the second material and configured to create regions of different thermal conductivity in the body, such as configured to create distinct nucleation regions within a material formed within the mold. A method for forming a ceramic article can include providing a slurry within a mold and freeze-casting the slurry to form a ceramic article having a burst-like distribution of porosity. A ceramic article according to embodiments herein can include a burst-like distribution of porosity.
