Difference between Schottky defect and Frenkel defect

1. Schottky defect is due to equal number of cations and anions missing from lattice sites. Frenkel defect is due to missing of ions (usually cations) from the lattice sites and these occupies interstitial sites.

2. Schottky defect results in decrease in density of crystal. Frenkel defect has no defect on the density of crystal.

3. Schottky defect is found in highly ionic compounds with having cations and anions of same sizes. Example: NaCl, CaCl. Frenkel defect is found crystal with low coordination number. Example: Agl, Zns.
