Abstract
In one inventive concept, a product includes a three dimensional ceramic structure having an open cell structure with a plurality of pores, wherein the pores connect through the ceramic structure from one side of the ceramic structure to an opposite side of the ceramic structure.
Claims25
A product, comprising:
- a three dimensional ceramic structure having an open cell structure with a plurality of pores, wherein the pores connect through the ceramic structure from one side of the ceramic structure to an opposite side of the ceramic structure, wherein an average diameter of the pores is in a range of about 10 nanometers to about 1000 nanometers.
A method of forming a porous ceramic structure, the method comprising:
- combining metal oxide nanoparticles and a polymer to create a slurry mixture;
- forming a body of the slurry mixture;
- curing the formed body for crosslinking the polymer;
- heating the formed body to a first temperature for removing the polymer from the formed body;
- and
- heating the formed body to a second temperature for sintering the formed body of the metal oxide nanoparticles, thereby creating a porous ceramic structure having an open cell structure with a plurality of pores, wherein the pores connect through the ceramic structure from one side of the ceramic structure to an opposite side of the ceramic structure.
3 more elements
A product, comprising:
- a three dimensional (3D) ceramic structure having a predefined shape characteristic of formation by additive manufacturing processes,
- wherein the ceramic structure has an open cell structure with a plurality of pores, wherein the pores connect through the ceramic structure from one side of the ceramic structure to an opposite side of the ceramic structure,
- wherein an average diameter of the pores is in a range of about 10 nanometers to about 1000 nanometers.
