Abstract
Nanocomposite ceramic or glass materials are disclosed herein, which include a matrix material and one or more nanostructures dispersed within the matrix material. The nanostructures may comprise one or more core-shell nanostructures including a core nanostructure and a shell material. The shell material may be different from the material making up the core nanostructure and may improve the wettability of the core-shell nanostructure, the dispersion of the core-shell nanostructure within the matrix material, or make the core-shell nanostructure more resistant to oxidation, when compared to the core nanostructure alone. Methods of making nanocomposite ceramic or glass materials are also disclosed herein.
Claims18
A nanocomposite ceramic or glass material, comprising:
- one or more matrix materials;
- and
- one or more nanostructures dispersed with the matrix material;
- wherein the one or more nanostructures comprises a core-shell nanostructure.
A method of forming a nanocomposite ceramic or glass material, comprising:
- (a) mixing:
- (i) raw matrix powder(s), (ii) nanostructure powder(s), and optionally (iii) one or more viscosity-reducing materials;
- (b) dispersing the raw matrix powder(s), nanostructure powder(s), and, optionally, the one or more viscosity-reducing materials in a solvent to form a nanostructure dispersion;
- (c) agitating the nanostructure dispersion to form a slurry;
- (d) drying the slurry to form a mixed powder;
- (e) melting the mixed powder;
- and
- (f) cooling the melted mixed powder to form the nanocomposite ceramic or glass material;
- wherein the nanostructure powder(s) comprises a core-shell nanostructure.
