Microstructure and physical properties of transparent thoria-yttria ceramics

The ceramics have low porosity (close to zero); higher than usual electrical conductivity, with activation energy of 1.12 eV; a relative permittivity ofapproximately 33; and single-phase fluorite-type cubic structure, confirmed by Raman and ir spectra.
