Formation of both tetrahedral and octahedral voids

Vedclass · Answer

(C) When we place a second layer over the first layer such that the spheres of the second layer are placed in the depressions of the first layer,voids are formed.- $Tetrahedral$ $voids$ are formed when a sphere of the second layer rests above the triangular void of the first layer.- $Octahedral$ $voids$ are formed when the triangular voids of the first layer and the second layer align such that they do not overlap,creating a space surrounded by $6$ spheres.- Thus,both $tetrahedral$ and $octahedral$ voids are formed in a $3D$ close-packed structure.

Explain the formation of voids during the transition from a two-dimensional hexagonal close-packed layer to a three-dimensional close-packed structure.
