Abstract
Official abstract text for this publication.
A multiphase composite, formed by freeze-casting, lyophilization, and sintering, has sintered particles forming a scaffold having at least one region of aligned porosity; and a second phase formed in pores of the scaffold. In a particular embodiment, the second phase is a nuclear fuel, in another, the first phase is a nuclear fuel, and in others, both phases are nuclear fuels. In some embodiments, the first phase is a ceramic, and in other embodiments a metal such as stainless steel. In other embodiments, the second phase is a metal, and in other embodiments a ceramic. In some embodiments the second phase is positioned in a subset of pores of the scaffold, at least some additional pores being filled with a third phase. In embodiments, the second phase is also sintered.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal/metal-oxide composite, comprising: sintered metal particles forming a scaffold, the scaffold having at least one region of aligned porosity with a gradient; and a metal-oxide ceramic material disposed in pores of the scaffold. 2. The metal/metal-oxide composite of claim 1 wherein the metal-oxide ceramic material comprises a nuclear fuel comprising uranium oxide. 3. The metal/metal-oxide composite of claim 1 where the metal is stainless steel.
