Journal of Materials Science, 1998
Investigation of electrical, mechanical and microstructural properties of ZnO–NiO two-phase ceramics with respect to the ageing process of the material were performed. Two constituent phases, ZnOss and NiOss were identified in those ZnO–NiO ceramics which exhibit a positive temperature coefficient of electrical resistivity (PTCR anomaly). The origin of

Aging behavior in Ba0.7Sr0.3Ti0.97Zr0.03O ceramics
Journal of Applied Physics, 2005The polarization aging behavior of the Ba0.7Sr0.3Ti0.97Zr0.03O3 ceramic that presents diffuse phase transition, was investigated at different temperatures. The aging of this system is explained by assuming the existence of two different relaxation regimes, one associated with rapidly relaxing polarized macroregions (τ1) and the other to long time ...

Ageing of dental zirconia ceramics
Journal of the European Ceramic Society, 2012Abstract An in vitro study was designed to monitor the t–m transformation of biomedical grade 3Y-TZP ceramics produced from two ready-to-press granulated powders of the same nominal chemical composition, but differing in their specific surface area.

Aging of thin polyimide-ceramic and polycarbonate-ceramic composite membranes
Industrial & Engineering Chemistry Research, 1993The gas-transport properties of several polymer-ceramic composite membranes with glassy polymer layers having effective thicknesses of approximately 4000 A exhibit strongly time-dependent behavior. The membranes, prepared from polyimide and polycarbonate, demonstrated decreases in gas flux of 40-60% in the first 20 days following manufacture.
