Phase transitions in undoped BaCeO3
Autor: Anton V. Kuzmin, F.W. Poulsen, M. Glerup, B. A.-T. Melekh, V. P. Gorelov
Publikováno v: Solid State Ionics. :13-22
The linear thermal expansion (370–1500 K) and electrical conductivity (950–1220 K) have been measured for undoped BaCeO3 in dry air, pH2O=40 Pa. Samples were made both by conventional sintering and by solidification from inductive melting. Raman

Oxygen ion conduction in ternary zirconia mixtures: Effect of SrO on MgSZ
Autor: F.W. Poulsen, J.B. Bilde-Sørensen, M. Hartmanová, G.G. Knab, K. Ghanbari-Ahari
Publikováno v: Solid State Ionics. :947-951
Magnesia stabilized zirconia (9, 13.5 and 17 mole% MgO) with and without 0.3 w/o strontia additions have been investigated by impedance spectroscopy and X-ray diffractometry. Sr addition has a significant influence on preserving the cubic form of zir

The effect of different internal surfaces in composite lithium electrolytes
Autor: F.W. Poulsen
Publikováno v: Journal of Power Sources. 20:317-325
A linear increase in the conductivity of LiI—alumina composite electrolytes with increasing specific surface area (2.4 – 260 m 2 g −1 ) of the alumina is demonstrated. Part of the enhanced conductivity is probably due to normal doping of the Li

NMR studies of lithium iodide based solid electrolytes
Autor: R. Dupree, F.W. Poulsen, A. Hooper, J.R. Howells
Publikováno v: Solid State Ionics. :131-133
In mixture of LiI with γAl2O3 the ionic conductivity is found to increase by up to three orders of magnitude over pure LiI. NMR measurements of7Li relaxation times were performed on both anhydrous LiI and a mixture of LiI with 30m/o γAl2O3. The rel

The large penetration power of high-energy X-rays (60 keV) raises interesting prospects for new types of structural characterizations of polycrystalline materials. It becomes possible in a non-destructive manner to perform local studies, within the b
