The existing of oxygen nonstoichiometry in complex lithium oxides
(Trans Tech Publications, 2013)
The possibility of oxygen deficiency in lithium-based complex oxides particularly for layered rock salt structures has little attention in the literature, in spite of the importance of these materials as potential lithium ...
Dielectric properties of barium titanate with different stoichiometry
(Trans Tech Publications, 2013)
This paper focused in details about dielectric properties of BT with different stoichiometry. In this research, BT was synthesis by solid state reaction between TiO2 and BaCO3 at constant sintering temperature of 1350 °C. ...
Determination of interlayer mixing and oxygen non-stoichiometry in LiNi0.8Mn0.1Co0.1O2-δ using powder diffraction data
(Trans Tech Publications, 2013)
The effect of preparation conditions, temperature and atmosphere, on oxygen stoichiometry and interlayer cation mixing in the layered rock salt material LiNi0.8Mn0.1Co0.1O2-δ has been investigated using X-Ray powder ...
A brief review of layered rock salt cathode materials for lithium ion batteries
(Trans Tech Publications, 2013)
Nowadays, many researchers have been studying on the layered rock salt-type structure as cathode materials for the lithium ion batteries. LiCoO2 is the most commonly used cathode material but Co is costly and toxic. Thus, ...
Electrical properties of fresnoite Ba2TiSi2O8 using impedance spectroscopy
(Trans Tech Publications, 2013)
Fresnoite with composition Ba2TiSi2O8 (B2TS2) was first found in 1965, adopting a non-centrosymmetric structure. It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible ...
Ferroelectric and relaxor ferroelectric to paralectric transition based on Lead Magnesium Niobate (PMN) materials
(Trans Tech Publications, 2013)
First ferroelectric materials were found in Rochelle salt was in a perovskite structure. Lead Magnesium Niobate (PMN) is a perovskites with a formula of PbMg1/3Nb2/3O3 (PMN) and are typical representatives for most of all ...
