Fabrication of Uranium Doped Yttrium Aluminium Garnets: Brian Bettes1; Yi Xie1; 1Purdue University
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.
Determination of Structural Parameters of Solid Solutions Type Ba1-3XGd2XTi1-3XEu4XO3.

Solid ceramic solutions Ba1-3XGd2XTi1-3XEu4XO3 (where, x = 0.1%, 0.15%, 0.3% and 0.6% by weight) were sintered by the solid state reaction method at 1300 ° C for 6 hours. The structural evolution was investigated by x-ray diffraction (XRD). Analysis of the full width at half height, the lattice parameters a and b, the tetragonality ratio (c / a), as well as the volume of the crystal structure indicate that all samples have a tetragonal structure at room temperature. The value of the tetragonality ratio (c / a) increases or maintains its value with the increase of the dopant. On the other hand, the volume of the crystalline structure decreases with the increase of the dopant except at x = 0.15% where the volume of the crystalline structure increases. The changes in the previous parameters are directly related to the dielectric properties that will be studied in the future work.
