Question

what are voids ? discuss tetrahedral and octahedral interstitial voids in a closed packed arrangement.​

Answer 1

Answer:

Inter particle vacant spaces in a three dimensional crystal lattice are called voids.

(a) Vacant space among four spheres having tetrahedral arrangement is called tetrahedral void and Its C.N. is 4.

(b) The vacant space form by placing six sphere at vertices of octahedral is called octahedral void. Its C.N. is 6.
