A very stable structure can be created, if we rotate around a hexagonal magnet ring, a linear chain so as to create an outer ring with a closed magnet arrangement. We can add as many outer rings as we want. In this way, a closed configuration CP is created which is the basis for the creation of the structures CCP and HCP. We start with a HP Hexagonal Packing structure. Then add another layer above with the same polarity so that each sphere contacts three spheres of the previous surface. Place another layer so that it is just above the first plane and with the same polarity. In this way a closed and very stable structure has been created, which has all the features of the HCP structure. Site view. Representative examples of the metals that crystallize in the HCP structure are Magnesium, Cadmium, Titanium and Zinc. Watch some photos and videos of Magnesium taken with Crystal Viewer The FCC lattice of Magnesium. The FCC lattice of Magnesium.
