Dense lanthanum silicate oxyapatite ceramics obtained by uniaxial pressing and slip casting
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...

| description | 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 1400ºC, 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. |
