Question

write any four difference between schottky defect and frenkel defect

Answer 1

Answer:

Schottky defect:

1. it occurs when the atoms are totally missing from the crystal lattice.

2. it generally occurs in crystal lattice due to the size of ratio of cation and anion in 1 .

3. there is decrease in density of the crystal.

4. two atoms are removed from the lattice for 1 singal defect.

frenkel defect:

1.it occurs when the atoms are just displayed from the position to some voids of crystal lattice.

2.it occurs generally in the lattice where the size of ratio of cation and anion is large.

3.the density of the crystal is unaffected.

4.one vacancy is created and one interstitial site occupied.
