Ethanol is added to a mixture solution produced by adding a surfactant solution to a peroxotitanic acid aqueous solution to produce precipitates, and the precipitates collected from the mixture solution are let dried to produce precursor powders 5. The precursor powders 5 are calcined at a predetermined temperature. Accordingly, a microstructure 2 can be produced which is formed of monophasic Ti4O7 in nano size. The microstructure 2 of monophasic Ti4O7 produced in this fashion can be fine-grained in nano size unlike prior-art crystals.

  • Publication number: 20150072863
    Abstract: Known processes for the production of nanoparticles of compounds of the transition metals Zr, Ti, Ta, rare earths (RE), Mn, and Fe via microemulsions lead to products that contain impurities from the reactants, particularly water, which make the further use of said nanoparticles difficult, for instance in high-temperature super conductors (HTSC). It is proposed that the nanoparticles be produced via anhydrous microemulsions having an outer phase composed of a nonpolar solvent and inner phase composed of a polar anhydrous solvent. The nanoparticles thus obtained exhibit good monodispersity and can be used in the production of REBa2Cu3O7 super conductors by incorporation into the precursor coating solution.

    Abstract: Some embodiments include methods of forming memory cells. Metal oxide may be deposited over a first electrode, with the deposited metal oxide having a relatively low degree of crystallinity. The degree of crystallinity within the metal oxide may be increased after the deposition of the metal oxide. A dielectric material may be formed over the metal oxide, and a second electrode may be formed over the dielectric material. The degree of crystallinity may be increased with a thermal treatment. The thermal treatment may be conducted before, during, and/or after formation of the dielectric material.
