Abstract
The attractive properties of Yttria doped ceria, particularly the structural and material properties, have led to vast research
efforts to investigate and develop such materials. One of the main applications of this ceramic is in the IT-SOFC. The aim of
this paper is the preparation and characterization of Y doped Ceria and low doped α-Al2O3, a new composite for IT-SOFC
(10 mol %) Y:CeO2 and (150 ppm) Y:α-Al2O3 composite were obtained by sol-gel or mechanical route for 10YDC and 150
Y:α-Al2O3. Shapes, size distributions and the mean of grains were determined by SEM, EDX and statistical investigations..
Keywords
Ceramic composite, Y:CeO2, Y:Al2O3.
