The dependence of grain‐boundary resistivity and resistance per square centimeter of grain‐boundary surface on grain‐boundary density (D) in yttria‐stabilized zirconia was investigated using reported data. The grain‐boundary resistivity increased with increasing D in the high‐D region but was independent of D in the low‐D region. These results were interpreted in terms of intrinsic effects such as lattice irregularity and extrinsic effects such as impurity segregation.
