Right option for the number of tetrahedral and octahedral voids in hexagonal primitive unit cell are:

Options

  1. A8 ,   4
  2. B6 ,   12
  3. C2 ,   1
  4. D12 ,   6

Correct answer

D. 12 ,   6

Step-by-step solution

In HCP Structure, Z = 6 Per sphere, there are two tetrahedral voids and one octahedral voids are present in the close packing structures. Tetrahedral voids = 12 Octahedral voids = 06 Hence, the correct answer is (D)
