Question

how are tetrahedral and octahedral voids formed ? draw diagram showing both type of voids?​

Answer 1

Answer:

Tetrahedral voids are triangular in shape. When two such voids combine, from two different layers they form an octahedral void. So when the tetrahedral void of the first layer and the tetrahedral void of the second layer align together, they form an octahedral void. Here the void forms at the center of six spheres.

To calculate octahedral void, if the number of spheres in a structure is “n”, then the number of octahedral voids will also be the same. i.e. “n”
