Answers (1)


Dodecahedral voids are not a type of interstitial voids. Tetrahedral, octahedral, and cubic voids are the three main types of interstitial voids found in crystal lattices. Tetrahedral voids are formed when four spheres are arranged tetrahedrally, octahedral voids are formed when six spheres are arranged octahedrally, and cubic voids are formed when eight spheres are arranged cubically.
