Abstract Scope |
Polycrystalline transparent ceramics have advantages over the equivalent single crystal material, due to reduced production time, decreased cost, and enhanced mechanical properties. Yttrium aluminum garnet (YAG) is one such transparent ceramic which has gained attention for its applications in solid state lasers. The garnet has been widely used as a host material for lanthanide series elements, such as neodymium doped YAG (Nd:YAG) that is widely applied in industrial laser applications. The uranium (U) doped YAG has gained interest as it allows for thermal or fast neutron flux to pump the laser, and thus to be used in reactor power detection instruments. However, the fabrication of U:YAG is rarely reported and understanding of its microstructural characteristics is lacking. We report on the fabrication of transparent U:YAG through the co-precipitation method and sintering in a vacuum furnace and present the microstructural characteristics of this material with X-ray diffraction and scanning electron microscope. |
