Autor: P.-A. Goujon, M. Mouyane, J. El Fallah, J. Bernard, D. Houivet

Publikováno v: Open Ceramics, Vol 19, Iss , Pp 100613- (2024)

In this study, nanoparticles of perovskiteCaZrO3 were prepared by a solution combustion technique using urea, glycine, β-alanineand citric acid as fuels. The aim of this work is to estimate the effect of these different fuels on the structure and mi

International audience; We report on the microfabrication process of free-standing suspended micro-bridges made of La0.7Sr0.3MnO3 (LSMO) thin films of thicknesses in the range of 10–100 nm. LSMO films were epitaxially grown on either SrTiO3 or CaTi

MgTiO3 for Cu base metal multilayer ceramic capacitors

Autor: David Houivet, J. El Fallah, Jean-Marie Haussonne, Jérôme Bernard

Publikováno v: Journal of the European Ceramic Society. 24:1877-1881

The evolution of the cost of palladium justifies studies devoted to the use of cheap base metals as electrodes for multilayer ceramic capacitors. In a precedent [ J. Eur. Ceram. Soc. 10–11(2001) 1681] work we investigated on Mn acceptor together wi

Effects of acceptor and donor additives on the properties of MgTiO3 ceramics sintered under reducing atmosphere

Autor: Jean-Marie Haussonne, B. Deneuve, J. El Fallah, C. Vigreux

Publikováno v: Journal of the European Ceramic Society. 21:1681-1684

Sintered in reducing atmospheres, MgTiO 3 ceramics are known to own ionised oxygen vacancies and conduction electrons which give rise to very poor insulation resistance. Prompted by the example of BaTiO 3 ceramics where acceptor doping agents can tra

(1-x)La 2/3 TiO 3 -xTiNiO 3 ceramics with x ranging from 0.01 to 0.2, were elaborated by conventional solid-state reaction starting from TiO 2 , La 2 O 3 , and NiO powders. These compositions have been identified as secondary phases detected in (Zr,S

Oxide slurries stability and powders dispersion: optimization with zeta potential and rheological measurements

Autor: J.-M. Haussonne, David Houivet, S. Vallar, D. Kervadec, J. El Fallah

Publikováno v: Journal of the European Ceramic Society. 19:1017-1021

Slurries stability and powder dispersion are highly dependent on both the pH and their density. The analysis of these parameters allows us to keep the slurries defloculated, leading to an optimum mix of powders before calcination and reaction. The pr
