Fabrication and characterisation of nickel/yttria stabilised zirconia cermet anodes for solid oxide fuel cells
… and morphological characterisation. Nickel/yttria stabilised zirconia (YSZ) cermet systems are employed as anode materials in high temperature solid oxide fuel cell (SOFC) applications. The ionically conducting YSZ powder was modified, by sintering and milling to vary the particle …

Grain boundary networks in RABiTS based YBa2Cu3O7[-delta] coated conductors
… a buffer layer system composed of CeO2 and yttria-stabilised zirconia, and subsequently a YBa2Cu3O7[-delta] film were epitaxially grown by pulsed laser deposition on a biaxially textured metallic substrate. The resulting texture of the YBa2Cu3O7[-delta] film is crucial for the achievement of …

The effect of bond coat oxidation on the microstructure and endurance of two thermal barrier coating systems
… coat applied by two different techniques and a yttria stabilised zirconia topcoat applied by electron beam physical vapour deposition (EBPVD). The bond coats were applied by either high velocity oxy-fuel spraying (HVOF) or EBPVD. Isothermal oxidation tests were carried out at 950°C, 1050°C and …

Thermal Evolution of MAS, YSZ and GZO Thermal Barrier Coating Materials in Benign and CMAS Rich Environments
… engines. However, the conventional choice, yttria-stabilised zirconia (YSZ), exhibits vulnerabilities, such as sintering induced stiffening, phase transformations, and susceptibility to molten siliceous debris. This study investigates the potential of magnesia-alumina spinel (MAS) as an …

A study of mechanochemical activation in solid-state synthesis of advanced ceramic composites
… milling method from earlier tests, wherein Yttria-stabilised zirconia (YSZ) and ceria were also added as dopants to study the possible effects on sintering behaviour and the resultant microstructure of the composite material. Mechanochemical milling of cordierite precursors mixed with …

The effect of radiation damage by fission fragments on the structural stability and dissolution of the UO2 fuel matrix
… single crystal LSAT (Al10La3O51Sr14Ta7) and YSZ (Yttria-Stabilised Zirconia) substrates. The CeO2 thin films were deposited onto single crystal silicon (001) substrates. Part of the bulk UO2 and CeO2 samples, the thin films of UO2 on the LSAT substrates and the thin films of CeO2 were irradiated …
