Determinación de la presencia de fatiga mecánica en materiales cerámicos

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 1999
It is well known that ceramic materials are highly susceptible to environmental assisted subcritical crack growth. In addition, this subcritical crack growth could be also related to cyclic loading (mechanical fatigue).

Modulación composicional en la perovskita “PbCrO3” y su influencia en las propiedades

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2010
In this work, we revisited the “PbCrO3” perovskite. In the late 60’s, it was claimed to be cubic and a G-type antiferromagnetic material (1, 2). We have encountered that an intrinsic compositional modulation is present and shows a deficiency in lead of ...

Thickness-dependent piezoelectric behaviour and dielectric properties of lanthanum modified BiFeO3 thin films [PDF]

open access: yesProcessing and Application of Ceramics, 2011
Bi0.85La0.15FeO3 (BLFO) thin films were deposited on Pt(111)/Ti/SiO2 /Si substrates by the soft chemical method. Films with thicknesses ranging from 140 to 280 nm were grown on platinum coated silicon substrates at 500°C for 2 hours.
