Investigating Phase and Electrical Properties of Calcium-Doped Yttrium Iron Garnet
Abstract
<jats:p>Literature studies have shown that Ca<jats:sub>0.5</jats:sub>Y<jats:sub>2.5</jats:sub>Fe<jats:sub>5</jats:sub>O<jats:sub>12-δ</jats:sub> can be a promising cathode material for intermediate temperature solid oxide fuel cell (IT-SOFC) <jats:sup>1</jats:sup>. As it exhibits higher electrical and ionic conductivity compared to several other kinds of rare-earth garnets <jats:sup>2</jats:sup>. However, given the high resistivity (> 10<jats:sup>12</jats:sup> Ω cm at room temperature) and less-explored oxide ion conductivity of its parent phase yttrium iron garnet (Y<jats:sub>3</jats:sub>Fe<jats:sub>5</jats:sub>O<jats:sub>12</jats:sub>, YIG), the effect of calcium doping on the electronic and ionic properties has not been fully studied yet <jats:sup>3</jats:sup>. In this work, polycrystalline samples of Ca-doped YIG, with general chemical formula Ca<jats:sub>x</jats:sub>Y<jats:sub>3-x</jats:sub>Fe<jats:sub>5</jats:sub>O<jats:sub>12-δ</jats:sub> (x=0, 0.1, 0.3, 0.5 and 0.7), were prepared and phase characterized by powder X-ray diffractometer. The oxygen non-stoichiometry was determined by iodometric titration at room temperature and thermogravimetric analysis (TG) at elevated temperatures. Total electrical conductivity was measured by four-probe DC method, and ionic conductivity was calculated by using a modified Hebb-Wagner polarization method. As a result, the ionic transference number was calculated and discussed in relation to its potential applications. </jats:p><jats:p>Reference: <jats:list list-type="simple"><jats:list-item><jats:p>Zhong, W., Ling, Y., Rao, Y., Peng, R. & Lu, Y.
