Mr Ten Divergence Betwixt Schottky Defect In Addition To Frenkel Defect (Schottky Defect In Addition To Frenkel Defect)
Schottky defect arise when equal publish of cations in addition to anions are missing from the lattice. It is a mutual defect inwards ionic compounds of high coordination number* where both cations in addition to anions are of the same size. Due to this density of crystal decreases in addition to begins to acquit electricity to a smaller extent.
Examples: KBr, NaCl KCI
Frenkel defect arises when closed to of the ions of the lattice occupy interstitial sites leaving lattice vacant. This defect to a greater extent than frequently than non establish inwards ionic crystals where anion is much larger inwards size than the cation. Due to this density does non alter inwards overall composition of the crystal.
Examples:Zns, AgBr
Schottky Defect vs Frenkel Defect
Schottky Defect 1. Equal publish of cations in addition to anions are missing from the lattice sites.
2. Found inwards highly ionic compounds amongst high coordination numbers in addition to where the cations in addition to anions are of like size.
3. Density of the enterprise decreases
Frenkel Defect
1. Influenza A virus subtype H5N1 cation leaves the normal lattice site in addition to occupies an interstitial site.
2. Found inwards ionic compounds amongst depression coordination numbers in addition to where the anions are much larger inwards size than cations.
3. Density of the enterprise remains the same.
* coordination number: It is defined equally the publish of nearest neighbours of a particle inwards a closed packed structure.
