The packing efficiency is maximum for the fcc
Webb26 maj 2024 · However, there is no need to differentiate between the fcc-structure and the hexagonal closest packed crystal (hcp), since in both cases they built up by densest packed atomic planes (for further information see post on Important lattice types). The packing density in the hcp-lattice thus also has the maximum possible value of 74 %. Webb7 juli 2024 · The packing efficiency is the fraction of the crystal (or unit cell) actually occupied by the atoms. It must always be less than 100% because it is impossible to pack spheres (atoms are usually spherical) without having some empty space between them.
