PREPARATION AND ELECTRICAL PROPERTIES OF A MONOPHASIC ZrO2-Y203-Bi203 SOLID ELECTROLYTE

چکیده
A preparation method is described of monophasic y t t r i a s tab i l ized zirconia doped with Bi203. This material is prepared from a homogeneous power which, a f te r pressing, is sintered in a Bi203 atmosphere. The resu l t ing ceramic has a composition of 0.78Zr02-0.206 YO1.5-O.O14Bi01. 5. The grain boundaries are enriched with bismuth. A re la t i ve density of 95% of the theoret ica l one is a t ta in ed at a considerably lower temperature than the bismuth free sample. The e lec t r i ca l conduct iv i t ies of the monophasic Bi doped and the Bi f ree e lec t ro l y te material do not d i f f e r s ign i f i can t l y .

Fabrication of Copper and Iron Nano/Micro Structures on Semiconducting Substrate and Their Electrical Characterization
In this paper, we have studied the electrical properties of the randomly distributed metallic (Co and Fe) nano/ micro wires on Silicon substrate. Deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the Si substrate. Spin coated films were irradiated with 150MeV Ni (+11) ions at a fluence of 8E7 ions/cm2, followed by UV irradiati...

(YCa)(TiMn)O3-d ceramics prepared using a reaction-sintering process were investigated. Without any calcination involved, the mixture of raw materials was pressed and sintered directly. Y₂Ti₂O₇ instead of YTiO₃ formed when a mixture of Y₂O₃ and TiO₂ with Y/Ti ratio 1/1 were sintered in air. Y₂Ti₂O₇, YTiO2.085 and some unknown phases were detected in Y0.6Ca0.4Ti0.6Mn0.4O3-d. Monophasic Y0.6Ca0.4...
متن کاملElectrode/electrol Yte Interfaces: Structure and Kinetics of Charge Transfer
When a metal is partly immersed in an electrolyte, a potential is set up across the two phases, i.e., at the electrode/electrolyte interface. The phases may be solids (metals or alloys, semiconductors, insulators), liquids (ionic liquids, molten salts, neutral solutions), or gases (polar or non polar). The more common terminology in electrochemistry is that a double layer is set up at the inter...
