摘要:
To provide a process for producing a phosphorescent body which allows efficient production of a granule-shaped phosphorescent body with a simple facility and a phosphorescent body produced by the process, and a nail stone including the phosphorescent body. In a process for producing a phosphorescent body containing at least a phosphorescent material and a glass material, at least the phosphorescent material and the glass material are mixed to give a paste mixture 2. A plurality of layers of the mixture 2 are stacked to form a granule-shaped laminate 3. The laminate 3 is sintered so that the laminate 3 is melted and shaped by the action of the surface tension of the melted laminate 3.

Methods for producing glass articles of a wide range of geometrical shapes, including shapes that are heretofore difficult or impossible to make monolithically. The glass articles are made by first building the nascent glass article from glass powder and a binder using a three-dimensional printing free-form fabrication process followed by sintering the nascent glass article at a temperature that is hundreds of degrees above the glass powder composition's glass transition temperature while supporting the nascent glass article in a bed of an inert powder having a high flowability.

The invention relates to solid-state electrolytes for use in lithium-air batteries or in lithium-water batteries. It is the object of the invention to provide solid electrolyte for use in lithium-air batteries or lithium-water batteries, with the solid electrolyte having sufficient strength, good conductivity for lithium ions, imperviousness for gas and water resistance and being inexpensive in manufacture. The solid-state electrolyte in accordance with the invention has an open-pore ceramic carrier substrate. In this respect, at least one layer which is conductive for lithium ions, which has an electrical conductivity of at least 10−5 Scm−1 and which is gas-impervious is formed on the surface facing the cathode. In this respect, the carrier substrate has greater mechanical strength and a larger layer thickness than the at least one layer.

For the production of mirrors for EUV lithography, substrates are suggested having a mean relative thermal longitudinal expansion of no more than 10 ppb across a temperature difference ΔT of 15° C. and a zero-crossing temperature in the range between 20° C. and 40° C. For this purpose, at least one first and one second material having low thermal expansion coefficients and opposite gradients of the relative thermal expansion as a function of temperature are selected and a substrate is produced by mixing and bonding these materials.

The present invention provides a fluorescent substance composite glass which is chemically stable, has a large size, is reduced in wall thickness, has a uniform thickness and therefore has a high energy conversion efficiency; a fluorescent substance composite glass green sheet and a process for producing the fluorescent substance composite glass. The fluorescent substance composite glass of the present invention is produced by baking a mixture containing a glass powder and an inorganic fluorescent substance powder, in which the energy conversion efficiency to a visible light wavelength region of 380 to 780 nm is 10% or more, when light having an emission peak in a wavelength range of 350 to 500 nm is applied.

A known SiO2 slurry for the production of quartz glass contains a dispersion liquid and amorphous SiO2 particles with particle sizes to a maximum of 500 μm, wherein the largest volume fraction is composed of SiO2 particles with particle sizes in the range 1 μm-60 μm, as well as SiO2 nanoparticles with particle sizes less than 100 nm in the range 0.2-15% volume by weight (of the entire solids content). In order to prepare such a slurry for use, and to optimize the flow behavior of such a slurry with regard to later processing by dressing or pouring the slurry mass, and with regard to later drying and sintering without cracks, the invention suggests a slurry with SiO2 particles with a multimodal distribution of particle sizes, with a first maximum of the sizes distribution in the range 1 μm-3 μm and a second maximum in the range 5 μm-50 μm, and a solids content (percentage by weight of the SiO2 particles and the SiO2 nanoparticles together) in the range 83%-90%.
