Question

AgBr shows both schottky and frenkel defect why?

Answer 1

Finally, the Ag+ ion is small in size in AgBr and therefore when removed from lattice point they can occupy interstitial sites and hence show both Frenkel and Schottky defects. ... Schottky defect arise due to missing of ions from their lattice point and frenkel arise when the missing ions occupy interstitial sites.
