Abstract: A method of bonding includes applying a glass composition to at least a first material surface. The glass composition includes a glass powder and a solvent. The first material surface is disposed onto a second material surface. An elevated temperature is applied to the first material surface and the second material surface to form a bond between the first material surface and the second material surface. The first material surface and the second material surface are compressed under an isostatic pressure.

Abstract: A nanocomposite optical ceramic (NCOC) material. The material having a first solid phase, a second solid phase, and a third solid phase. The first solid phase has first solid phase grains no larger than 5 μm, and each first solid phase grain has a first solid phase grain boundary. The second solid phase has second solid phase grains no larger than 5 μm, and each second solid phase grain has a second solid phase grain boundary. The third solid phase has a doping agent. The doping agent is less than 5 atomic % soluble in the first solid phase and the second solid phase. At least part of the third solid phase is situated at the second solid phase grain boundary.

Abstract: A method of making a scintillator material includes forming a dried ceramic composition into a ceramic body with a garnet crystal formula (Gd3-x-zYx)Cez(Ga5-yAly)O12, where x is about 0 to about 2, y is about 0 to about 5, and z is about 0.001 to about 1.0. The ceramic body is sintered to form a sintered ceramic body. The sintered ceramic body is surrounded by a powder mixture that includes a garnet powder. The density of the sintered ceramic body is increased by applying an increased temperature and isostatic pressure to form the scintillator material.

Abstract: A nanocomposite optical ceramic (NCOC) material includes a plurality of coated (core-shell) nanoparticles having nanoparticles of a first material coated with a coating of a second material. The first material and the second material are mutually insoluble and each have a transmissivity of at least 80% for an intended wavelength. The first material and the second material have a difference in index of refraction of less than 25%. The first material and second material have grins with a diameter of less than 1/20th the intended wavelength. The coating of the second material on the nanoparticles of the first material is up to 50 nm thick. The NCOC contains no more than 0.01% voids per unit volume.
