En este trabajo se estudia la fabricación y la caracterización estructural, microestructural y mecánica de compuestos de BaCeO3 dopado con itrio e iterbio (contenidos de 0-20 at%). Estos compuestos son de tipo perovskita (ABO3), donde el dopado con cationes trivalentes sustituyen a los cationes B4+ introduciendo simultáneamente vacantes de...

The high-temperature mechanical properties of the mixed ionic-electronic conductor perovskite BaCe0.95Y0.05O3-δ with average grain size of 0.40μm have been studied in compression between 1100 and 1300°C in air at different initial strain rates. The true stress-true strain curves display an initial stress drop, followed by an extended...

The increase of aesthetic demands, together with the successful outcome of current implants, has renewed interest in the search for new materials with enough mechanical properties and better aesthetic qualities than the materials customarily used in implanto-prosthetic rehabilitation. Among these materials, zirconium has been used in different...

Los dos objetivos fundamentales de la implantología moderna son la función y estética; objetivos que pueden alcanzarse gracias a los materiales cerámicos, ideales para reemplazar estructuras dentarias gracias a sus cualidades ópticas y su estabilidad intraoral a largo plazo. La circona presenta propiedades mecánicas muy parecidas a la de los...

Objectives: This study was undertaken to characterize the mechanical response of bare (as-received) and single layer ceramized zirconia abutments with both internal and external connections that have been developed to enhanced aesthetic restorations. Material and Methods: Sixteen zirconia implant abutments (ZiReal Post®, Biomet 3i, USA) with...
