Abstract
Embodiments of the disclosure relate to a sintered ceramic article. The sintered ceramic article includes sintered ceramic particles. The sintered ceramic particles include a shell at least partially surrounding at least one core. The shell is made from a first ceramic phase, and the at least one core is made from a second ceramic phase. The first ceramic phase differs from the second ceramic phase in at least one of density, composition, or pore morphology.
Claims20
A sintered ceramic article, comprising:
- sintered ceramic particles, the sintered ceramic particles comprising a shell at least partially surrounding at least one core;
- wherein the at least one core comprises a first ceramic phase and the shell comprises a second ceramic phase;
- wherein the first ceramic phase differs from the second ceramic phase in at least one of density, composition, or pore morphology.
A method, comprising:
- extruding a paste comprising ceramic particles to form a green structure, the ceramic particles comprising a shell at least partially surrounding at least one core, wherein the at least one core comprises a first ceramic phase and the shell comprises a second ceramic phase, and wherein the first ceramic phase differs from the second ceramic phase in at least one of density, composition, or pore morphology;
- firing the green structure to sinter the ceramic particles into a sintered ceramic article.
