Question
Compare and contrast Frenkel and Schottky defects.
Step 1
Frenkel defects occur when an atom or ion is displaced from its normal lattice position to an interstitial site, creating a vacancy at the original site. This type of defect typically involves cations in ionic crystals. Show more…

There are two types of intrinsic defects, Schottky and Frenkel defects. Explain the difference between these two defects, help your discussion by drawing two diagrams. [This must be written in your own words and not be taken directly from your notes or some other source.] [4 marks] For each of the following crystalline solids, state which you would expect to predominate Schottky or Frenkel defects: CsBr; KI, AgBr, CaF2 [2 marks]
Which of the following statements is correct in context of point defects in a crystal? (a) $\mathrm{AgCl}$ as well as $\mathrm{CaF}_{2}$ has Schottky defects (b) $\mathrm{AgCl}$ as well as $\mathrm{CaF}_{2}$ have anion Frenkel defects (c) $\mathrm{AgCl}$ has cation Frenkel defects and $\mathrm{CaF}_{2}$ has Schottky defects (d) $\mathrm{AgCl}$ has cation Frenkel defects and $\mathrm{CaF}_{2}$ has anion Frenkel defects
