High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

Creator:

Bowen, Michael S.

Abstract:

Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...

The Conduction Properties of Heavily Acceptor Doped Lead Zirconate Titanate Ceramics

Creator:

Sangwan, Vyomika

Abstract:

Heavily acceptor doped Pb1.02Dx(Zr0.5Ti0.5)1-xO3 ceramics, where A is the dopant, were investigated in this research. Dopants studied included iron, magnesium and manganese at mole concentrations x ≤ 0.20. X-ray diffraction data along with scanning electron microscopy images revealed the solubility limits of these ceramics. All doped compositions exhibited a shift...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:

Bowen, Michael S.

Abstract:

Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...
