Titanium (II) oxide has a rock salt structures. X-ray diffraction data shows that the length of one edge of the cubic unit cell for TiO with 1 : 1 ratio of Ti to O is 418 pm and the density is 4.92 g `cm^(-3)` . (Atomic mass of Ti = 48)
What is the type of defect?

A

Frenkel

B

Schottky

C

Both (A) and (B)

D

None of these

Text Solution

Verified by Experts

Theoretical density `D= (4xx64)/(N_(A)xxa^(3))= 5.82 "cm"^(-3) (D_("exp"))`.
Hence the ionic solid have the Schottky defect.
