A wavelength converter is provided with a light-transmitting substrate and with a thin film that is formed on a surface of the light-transmitting substrate and that contains a phosphor. A sintered body that constitutes the light-transmitting substrate has an average particle size of 5-40 μm. The light-transmitting substrate contains at least 10-500 ppm by mass of MgO. The principal component of the phosphor is an α-sialon that is indicated by the general formula (Ca.sub.α,Eu.sub.β) (Si,Al).sub.12(O,N).sub.16 (provided that 1.5<α+β<2.2, 0<β<0.2, and O/N≦0.04).

A method for manufacturing a three-dimensional fired body includes (a) a step of producing a shaping mold using an organic material, the shaping mold having a shaping space which has the same shape as a shaped body having a hollow portion that opens to an outer surface thereof, in which a core corresponding to the hollow portion is integrated with the shaping mold; (b) a step of producing the shaped body in the shaping mold by pouring a ceramic slurry into the shaping space and solidifying the ceramic slurry; (c) a step of drying and then degreasing the shaped body, in which the shaping mold is eliminated in any one of the following stages: before drying, during drying, after drying and before degreasing, during degreasing, and after degreasing of the shaped body; and (d) a step of firing the shaped body to obtain a three-dimensional fired body.

A sintering aid mixture for sintering solid-state ion conductors, electrode materials, or the like for solid-state batteries is provided. The mixture includes at least one sol-gel precursor and/or at least one sol-gel direct precursor produced from at least one sol-gel precursor.

The present invention relates to gels and processes for making bundles of aligned ceramic nanofibers, ceramic nanostructures made by such processes, and methods of using such ceramic nanostructures. Such process is templated via block copolymer self-assembly but does not require any post processing thermal and/or solvent annealing steps. As a result, such process is significantly more efficient and scalable than other processes that are templated via block copolymer self-assembly. The resulting fibers are aligned according to the direction of deposition, making steps where individual fibers are bundled unnecessary.
