Explain frenkel defect in crystalline solid?
Answers
Frenkel defect in crystalline solid occurs when an atom is moved from its lattice position to an interstitial site. This creates a vacancy in the original lattice position and also creates interstitial defect at the new position within the element without a change to the chemical properties.
The volume and mass of the element remain unchanged as the defect does not affect the density of the solid, it only involves the movement of the ions within the Crystals. Examples of crystalline solids that exhibit frenkel defects are: Silver (I) chloride and Zinc sulfide.
Frenkel defect is a crystalline solid defect which occurs when the molecules or ions move from the lattice position to the interstitial site.
It may or may not contain a void.
Examples solids showing frenkel defects are: Silver chloride and Zinc sulphide.
