Neodymium silicate apatites are promising intermediate temperature (500°C–700°C) electrolytes for solid oxide fuel cells. The introduction of Al promotes isotropic percolation of O2−, and at low levels (0.83–2.0 wt% Al) enhances bulk conductivity. To better understand the effect of Al-doping on intr...
