A hot pressing method involves the simultaneous application of high pressure (1. 5-8 GPa) at a relatively low temperature (0. 2-0. 6 T ) High compaction pressure causes particle deformation, such that the green density increases with pressure up to a maximum at about 8 GPa. Low sintering temperature mitigates grain growth during the consolidation process. Another factor that promotes densification is the occurrence of a pressure-induced phase transformation (typically from a metastable structure to a more stable structure), accompanied by a significant reduction in free volume for example greater than about 1 to about 2 vol. %. Such transformation-assisted consolidation has been successfully applied to produce sintered oxide and non-oxide bulk nanocrystalline ceramics having a grain size less than 100 nm, starting with even finer-scale ceramic nanopowders. Under appropriate high pressure conditions, a sintered grain size can be realized that is actually smaller than the original powder particle size.

A chemical synthetic route for nanostructured materials that is scalable to large volume production, comprising spray atomization of a reactant solution into a precursor solution to form a nanostructured oxide or hydroxide precipitate. The precipitate is then heat-treated followed by sonication, or sonicated followed by heat treatment. This route yields nanostructured doped and undoped nickel hydroxide, manganese dioxide, and ytrria-stabilized zirconia. Unusual morphological superstructures may be obtained, including well-defined cylinders or nanorods, as well as a novel structure in nickel hydroxide and manganese dioxide, comprising assemblies of nanostructured fibers, assemblies of nanostructured fibers and agglomerates of nanostructured particles, and assemblies of nanostructured fibers and nanostructured particles. These novel structures have high percolation rates and high densities of active sites, rendering them particularly suitable for catalytic applications.

This invention relates to methods whereby nanoparticle liquid suspensions are used in conventional thermal spray deposition for the fabrication of high-quality nanostructured coatings. Ultrasound is used for disintegration of the as-synthesized particle agglomerates, nanoparticle dispersion in liquid media, and liquid precursor atomization.

A thermal spray method for the fabrication of ceramic/metal and ceramic/ceramic hardcoating for wear applications. The method makes use of feedstock powder, composed of micron-scale aggregates of hard phase material particles that are either mixed or coated with a readily fusible nano-scale binder phase material. Thus, during thermal spraying, the nanostructured material undergoes rapid melting while the aggregated material is heated but not necessarily melted. A dense coating is formed when the molten nano-material fills the available pore spaces between the heated and softened aggregates, providing a strong and tough matrix for the consolidated material. Optimal wear properties are achieved when the volume fraction of aggregated particles is high, typically in the range of 0. 5-0. 9. Aggregated material may be composed of one, two or more particles of difference sizes and/or compositions, with particle size distribution that gives high packing density for the hard phase.

A new class of nanostructured RE-doped SiO-base materials that display superior fluorescence properties is provided. In particular, high gain combined with a broad and flat spectral band width is observed in material composed of a high fraction of a nano-dispersed metastable silicate phase in a glassy SiOmatrix, produced by partial devitrification (crystallization) of several glassy AlO/ErO- and YO/ErO-doped SiOcompositions. Also, a highly deconvoluted spectral emission, with several prominent peaks, is observed in completely devitrified material, consisting of a uniform nano-dispersion of an equilibrium silicate phase in a crystobalite SiOmatrix. Such enhanced fluorescence properties were observed in heat treated nanopowders prepared by vapor-phase, solgel, rapid solidification, and spray-pyrolysis methods.

A solid oxide fuel cell has anode, cathode and electrolyte layers each formed essentially of a multi-oxide ceramic material and having a far-from-equilibrium, metastable structure selected from the group consisting of nanocrystalline, nanocomposite and amorphous. The electrolyte layer has a matrix of the ceramic material, and is impervious and serves as a fast oxygen ion conductor. The electrolyte layer has a matrix of the ceramic material and a dopant dispersed therein in an amount substantially greater than its equilibrium solubility in the ceramic matrix. The anode layer includes a continuous surface area metallic phase in which electron conduction is provided by the metallic phase and the multi-oxide ceramic matrix provides ionic conduction.
