WebThe Schottky defect has occurred in those crystals in which the sizes of ions are almost similar. Frenkel defect has occurred in those ionic crystals in which sizes of ions (anions and cations) show large differences. Compounds such as KCl, KBr, CsCl, etc. show Schottky defects. Compounds such as NaCl, ZnS, AgI, etc. show Frenkel defects. WebMar 29, 2024 · First, Schottky defect occurs in the crystals where the size difference of cation and anion is small, although in the Frenkel defect size of anion is large as compared to that of the cation. Second, in the former one, both cation and anion leave the lattice, whereas in the latter one smaller ion (cation) leaves the lattice site. crysbellys
