Question

describe the schotty and Frankel defect found in ionic crystals. how these defects affects the properties of the crystals.​

Answer 1

Schottky defect occurs in those ionic crystals where difference in size between cation and anion is small. ... In Schottky defect, both cation and anion leave the solid crystal. In Frenkel defect, only the smaller ion (cation) leaves its original lattice site; whereas, the anion remains in original lattice sites.
