Question

difference between schottky and frenkel defect ​

Answer 1

Answer: Schottky- Missing of equal no.of cations and anions from the lattice site.

Its density decreases.

Frenkel-When one of the cation occupies the interstitial sites it is termed as frenkel. Mean the ion in the lattice only.

so,the density remains the same.

Answer 2

1)Schottky Defect: Schottky defect is a type of point defect that occurs due to loss of atoms from a crystal lattice in stoichiometric units.

Frenkel Defect: Frenkel defect is a type of point defect occurs due to loss of one atom or a small ion.

2)Schottky Defect: Schottky defect causes the density of the lattice to be reduced.

Frenkel Defect: The Frankel defect does not have any influence on the density of the lattice.

Schottky Defect: The mass of the lattice is reduced when Schottky defect occurs.

Frenkel Defect: The mass remains constant even after the Frenkel defect has occurred
