  • Patent number: 9126833
    Abstract: A method for the rapid and continuous production of crystalline mixed-metal oxides from a precursor solution comprised of a polymerizing agent, chelated metal ions, and a solvent. The method discharges solution droplets of less than 500 ?m diameter using an atomizing or spray-type process into a reactor having multiple temperature zones. Rapid evaporation occurs in a first zone, followed by mixed-metal organic foam formation in a second zone, followed by amorphous and partially crystalline oxide precursor formation in a third zone, followed by formation of the substantially crystalline mixed-metal oxide in a fourth zone. The method operates in a continuous rather than batch manner and the use of small droplets as the starting material for the temperature-based process allows relatively high temperature processing. In a particular embodiment, the first zone operates at 100-300° C., the second zone operates at 300-700° C., and the third operates at 700-1000° C., and fourth zone operates at at least 700° C.

  • Publication number: 20150010456
    Abstract: The present invention addresses the problem of providing producing processes for garnet precursor microparticles (a precursor for microparticles of garnet structure) and microparticles of garnet structure. One of the processing processes comprises mixing ions of at least two elements with a basic substances that contain the at least two elements. The thin-film fluid is formed between at least two processing surfaces which are approachably and separably arranged facing each other with at least one of the processing surfaces rotating relative to the other. In the processing process, the precipitated microparticles are garnet precursor microparticles, and the molar ratio between the at least two elements in the garnet precursor microparticles is regulated by controlling the pH of the thin-film fluid after the mixing. Microparticles of garnet structure can be obtained by subjecting the garnet precursor microparticles to heat treatment.

  • Publication number: 20140363365
    Abstract: A method for the rapid and continuous production of crystalline mixed-metal oxides from a precursor solution comprised of a polymerizing agent, chelated metal ions, and a solvent. The method discharges solution droplets of less than 500 ?m diameter using an atomizing or spray-type process into a reactor having multiple temperature zones. Rapid evaporation occurs in a first zone, followed by mixed-metal organic foam formation in a second zone, followed by amorphous and partially crystalline oxide precursor formation in a third zone, followed by formation of the substantially crystalline mixed-metal oxide in a fourth zone. The method operates in a continuous rather than batch manner and the use of small droplets as the starting material for the temperature-based process allows relatively high temperature processing. In a particular embodiment, the first zone operates at 100-300° C., the second zone operates at 300-700° C., and the third operates at 700-1000° C., and fourth zone operates at at least 700° C.

    Abstract: [Problem] The present invention relates to: a heat ray shielding adhesive which is used in bonding to a windowpane and the like and shields neat rays; a heat ray shielding transparent adhesive sheet; and a method for producing the heat ray shielding adhesive. The present invention provides a heat ray shielding transparent adhesive sheet which has nigh transmittance in the visible light region, low haze and more excellent transparency. [Solution] Transparency and heat ray shielding properties can be imparted in a simpler manner by using a heat ray shielding adhesive composition which contains fine heat ray shielding particles that have a half-value width of the first main peak of from. 0.01° to 0.80° (inclusive) as determined by X-ray diffraction pattern, and a heat ray shielding transparent adhesive sheet is therefore able to be produced at low cost.
