(2016). Electrical properties of reduced 3YTZP ceramics consolidated by spark plasma sintering. Ceramics International, 42 (6), 6713-6719.0272-8842https://hdl.handle.net/11441/721713 mol% Yttria doped zirconia ceramics were consolidated by spark plasma sintering (SPS) at two sintering temperatures with the aim of achieving two different reduction levels. Microstructural characterization of the ceramics was performed by scanning electron microscopy (SEM). Electrical properties were investigated by means of impedance spectroscopy from room temperature up to 500 °C. The two ceramics presented a remarkably different electrical behavior. The effect of the extra electrons introduced by reduction during SPS on both the bulk and the grain boundary conductivity was analyzed and discussed.application/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/ZirconiaSpark plasma sinteringImpedance spectroscopyElectrical conductivityinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1016/j.ceramint.2016.01.040
