Lanthanum Silicate

Lanthanum silicate oxyapatite (LSO) is a promising ion conductive ceramic material, which has higher oxygen ion conductivity at intermediate temperatures (600-800?C) compared to yttria-stabilized zirconia. Its mechanical properties, though important for any of its applications, have been scarcely reported. In this study, we compare apparent densification, open porosity and Vickers hardness of samples conformed by uniaxial pressing and slip casting and fired up to 1600?C. Colloidal processing was optimized for slip casting in order to get high green densities. At sintering temperatures higher than 1400?C, both processing routes yielded comparable densities, although uniaxially pressed samples show slightly better mechanical properties, evidencing that slip cast ones already underwent a grain growth process.

Yttria-stabilized zirconia (YSZ) thin films were deposited by pulsed laser deposition (PLD) at laser repetition frequencies of 10–50 Hz. Controlling the laser repetition frequency can achieve high deposition rate of YSZ, but high deposition rate at high laser repetition frequency can adversely affect the crystallinity of the resulting film. In the present work, X-ray diffraction (XRD) of YSZ thin films deposited at 10–50 Hz unexpectedly indicated no significant differences. Well-crystallized YSZ thin films were obtained for all laser repetition frequencies. This result may be due to a sufficient substrate temperature of 1000 K during processing. The oxide-ion conductivity of each thin film was comparable to that of bulk YSZ. Only minor differences in Y2O3 content, residual stress, grain size, and grain-boundary width were observed among the films. We concluded that similar quality YSZ thin films were obtained at all deposition frequencies. Oxide-ion conductivity was affected by the temperature at which the substrate was deposited. The YSZ thin films deposited at 900 K and 1000 K showed similar oxide-ion conductivity and films deposited at 800 K showed lower oxide-ion conductivity. This difference could perhaps be due to narrow grain-boundary width. The YSZ thin film with highest oxide-ion conductivity was fabricated at an intermediate substrate temperature of 900 K with a deposition rate of 86 nm·min−1 at 50 Hz, without additional high-temperature annealing greater than 1273 K. The YSZ growth rates were faster than the rates for other gas-phase methods such as midfrequency and DC sputtering.

The relationship between the optical phonon parameters and the oxygen ion conductivities were investigated for AlYb co-doped zirconia ceramics. Intrinsic intragrain ion conductivity, σdc, decreased with increasing Al loading into ytterbia-stabilized zirconia, while the damping parameter of the lattice vibration, γ1TO, increased. This phenomenon agreed with findings of our previous study, which revealed a relationship between the σdc and the γ1TO for zirconia-based ion conductors.
