Schottky defect	Frenkel defect
1. Equal number of cations and anions are missing from the lattice sites.	1. Mostly cation leaves the normal lattice site and occupies an interstitial site.
---	---
2. Found in highly ionic compounds with high coordination numbers.	2. Found in ionic compounds with low coordination numbers
3. Density of the solid decreases	3. Density of the solid remains the same.
4. The cations and anions are of similar size.	4. The anions are much larger in size than cations.
5. Dielectric constant is not affected.	5. Closeness of like charges increases dielectric constant.
