Effect of sintering time on the properties of LaYO3 doped with ZrO2 solid electrolyte
(Trans Tech Publications, 2013)LaYO3 doped-ZrO2ceramic with the composition La0.95Zr0.05YO3+δ was prepared via the solid state reaction. The samples were sintered at 1450 °C and sintering times in range of 6-15 hours have been varied for both doped and ... -
Ionic conductivity and crystal structure for the Li3−2xCr2−xTax(PO4)3 system
(Elsevier, 2004)The monoclinic phase (P21/n) was formed for 0≤x≤0.6 and the NASICON-type rhombohedral phase (R3̄c) was obtained for the region 0.8≤x≤1.2 in the Li3−2xCr2−xTax(PO4)3 system. The activation energy for Li+migration was ca. ... -
Solid electrolyte for intermediate temperature solid Oxide fuel cell
(Universiti Malaysia Perlis (UniMAP), 2020-06)Solid oxide fuel cell (SOFCs) have potential to generate high efficiency electrical energy converted from chemical energy with minimum impact to the environment. This thesis were aimed to study the structure and electrical ... -
Solid electrolyte for solid stat rechargeable lithium ion
(Universiti Malaysia Perlis (UniMAP)School of Materials Engineering, 2016)Solid electrolyte for solid state rechargeable Lithium ion battery by using Li6Zr2O7 as one new element that could contribute better life cycle to the lithium ion battery. It is focus on two major categories: crystalline ... -
Studies on the densification and grain growth mechanisms of Polycrystalline ceramic based on LaYO₃
LaYO₃ is a polycrystalline ceramic with the perovskite type oxide structure. LaYO₃ was prepared using solid state synthesis method. Initially, the sample was heated between 1200 °C to 1500 °C for 10 hours and slowly cooled ... -
Synthesis and characterization of Fe from different source doped 8YSZ for solid electrolyte in solid oxide fuel cell (SOFC)
(Universiti Malaysia Perlis (UniMAP)School of Materials Engineering, 2016-06)The samples from different sources of Fe in oxide form (pure iron oxide powders, Fe₂O₃) and Fe source from salt (iron nitrate, Fe(NO₃)₃) for different compositions (pure YSZ, 1FeYSZ, 2FeYSZ and 3FeYSZ) were prepared and ...
