Nanocrystalline Mgo

We investigated superfast densification of nanocrystalline MgO powders by spark plasma sintering (SPS) between 700 °C and 825 °C under applied pressures of 100and 150 MPa. Fully-dense transparent nanocrystalline MgO with a 52-nm average grain size was fabricated at 800 °C and 150 MPa for 5 min. In-line transmissionsof 40% and 60% were measured compared to MgO single crystal, for the yellowand red wavelengths, respectively. Densification occurs by particles sliding over each other; the nanometric grain size and pores lead to the optical transparency. The light brownish color of the nanocrystalline MgO is due to the oxygen vacancy color centers, originating from the reducing atmosphere of the SPS process.

Final Composition

The concept of the in situ engineering of nanoreactors – morphologically homogeneous aggregates of synthesized complex intermediate metastable products has been realized. The nanoblast calcination technique was applied and the final composition was synthesized within the preliminary localized volumes of each single nanoreactor. Such technique provided the heredity of the final structure of nanosize product, and allowed the prevention of the uncontrolled agglomeration and production of Gd20Ce80O1.90 powder consisting of ∼50 nm nano-aggregates of ∼7 nm crystallites with a remarkably homogeneous composition and uniform morphology. Finally, the SPS consolidation of nanosized aggregates of Gd20Ce80O1.90 was analyzed. The CGO nanoceramics with average grain sizes of 32 nm and 16 nm were obtained by low-temperature SPS at 1050 °C and 970 °C, respectively under the pressures of 90–150 MPa.
