Detailed Solution

A vacancy at an anion site causes a Schottky defect, which is naturally accompanied by a vacancy at a cationic site to maintain the system's electrical neutrality. The Schottky defect causes the crystal's density to drop as the amount of ions decreases. Due to the proximity of similar charges, the Frenkel defect raises the crystals' dielectric constant. The crystals' stoichiometric flaws improve their electrical conductivity. By using an ionic process, the crystals only slightly carry electricity.
