Yttria Stabilized Zirconia (YSZ) is of interest for many industries. Varying amounts of Yttria (Y2O3) can be doped into Zirconia (ZrO2) to create materials with specific characteristics. For instance, 3mol% YSZ (3YSZ) is known to be a super hard material and is used as a coating on drill tips and as an abrasive. Eight mol% YSZ (8YSZ) is commonly used as a solid electrolyte in Solid Oxide Fuel Cells because of its good ionic conducting abilities and stability at high temperatures. In this thesis project, a novel experimental setup was created and used to study the ionic conductivity of (3 …
Synthesis And High-Pressure Structural Studies Of Aux2 (X= Al, Ga, In) Compounds, Jason Lee Baker
Synthesis And High-Pressure Structural Studies Of Aux2 (X= Al, Ga, In) Compounds, Jason Lee Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
Three intermetallic compounds, AuX2 (X = Al, Ga, In), were synthesized by arc-melting proper stoichiometric ratios of high purity Au, Al, Ga, and In. They were found to be single-phase in the CaF2 type Fm3m crystalline structure. Interest in these particular intermetallic materials is due to intriguing pressure-induced behavior such as electronic topological transitions (ETTs), and structural phase transitions as well as their use in a variety of practical applications such as a solar spectral absorber and in electronic circuitry. In this study, the high-pressure structure of these materials was studied using high resolution synchrotron x-ray diffraction (XRD) …
