Influence of cationic vacancies on the ionic conductivity of oxyapatites

摘要

Oxyapatites are very promising materials in terms of ionic conductivity. They can be considered as a potential electrolyte for fuel cells as SOFC. Substituted silicated rare earth oxyapatites with formula La_(9.33+z/3-x)Me_x square_( 0.67-z/3)(SiO_4)_6O_(2+z/2-x/2) (z
