What type of crystal defect is indicated in the diagram below?
Frenkel defect
Schottky defect
interstitial defect
Frenkel and Schottky defects.
When an atom or ion is missing from its normal lattice site, a lattice vacancy is created. This defect is known as Schottky defect. Here equal number of Na + and Cl- ions are missing from their regular lattice position in the crystal. So it is Schottky defect.
