WebNov 13, 2024 · The HCP stacking shown on the left just above takes us out of the cubic crystal system into the hexagonal system, so we will not say much more about it here … WebHow is the packing density of HCP is calculated? Calculate the ratio c/a ratio for the ideal hexagonal close-packed structure. The ratio of c/a is 1.63 for He 4, 1.86 for Zn, and 1.58 for Ti. Compare these values to that for the ideal close-packed structure and speculate on the reasons for the deviations from the ideal structure.
