چکیده
In the present study, sintering behavior and electrical conductivity of Sm doped Ceria (SDC) multi-doped (Sm/Pr/Li) electrolytes synthesized by microwave-assisted co-precipitation method is studied. SDC green pellet displayed a unimodal shrinkage with linear 15.67% along slight dedensification above 1350℃. An increase in an temperature from 1200 to 1300℃ was observed. Further increasing (1400 1500℃) decreased, which could be due (as observed behavior). At 600℃, SDC1200 around 1.34 × 10 -2 S cm -1 . The drastically decreased 850℃ 1200℃ addition Li, increased Pr electrolytes. 3Li-SPDC850 sintered at 1.44 thermal expansion coefficient (TEC) studied were range 12.7 -6 17.6 K

15 صفحه اولOptimization of ionic conductivity in doped ceria.
Oxides with the cubic fluorite structure, e.g., ceria (CeO2), are known to be good solid electrolytes when they are doped with cations of lower valence than the host cations. The high ionic conductivity of doped ceria makes it an attractive electrolyte for solid oxide fuel cells, whose prospects as an environmentally friendly power source are very promising. In these electrolytes, the current i...
متن کاملBehavior of Viscosity and Thermal Conductivity
This paper reviews the experimental information on the behavior of the viscosity and thermal conductivity of fluids near the critical point. Section 2 presents some general remarks on experimental complications associated with the measurement of these properties in the critical region. Experimental work on the viscosity of one component fluids near the liquid-vapor critical point is rev...
متن کاملOptimizing ionic conductivity in doped ceria
David Andersson et al. report calculations revealing how doped oxides with cubic fluorite structures become effective ionic conductors. Cubic fluorite structures, such as ceria (CeO2), can become effective ionic conductors when doped with cations of lesser valence than the host cations. Doped ceria thus has potential as an electrolyte for environmentally friendly solid oxide fuel cells. Anderss...
متن کاملThermal conductivity behavior of boron carbides.
Knowledge of the thermal conductivity of boron carbide is necessary o evaluate its potential for high temperature thermoelectric energy conversion applications. We have measured the thermal diffusivity of hot -pressed boron carbide B1_xCx samples as a function of composition (0.1 < x < 0.2), temperature (300 K to 1700 K) and temperature cycling. These data in concert with density and specific h...
