Close Packed Structures: fcc and hcp Physics in a Nutshell
WebFeb 1, 2024 · In ionic solids, the bigger ions (usually, anions) form the close-packed structure and the smaller ions (usually, cations) occupy the voids. If the smaller ion is small enough then tetrahedral voids are occupied, if bigger, then octahedral voids are occupied. Not all octahedral or tetrahedral voids are occupied.
