WebTetrahedral voids are vacant gaps that are encompassed by four spheres, or simply, cells. Octahedral voids, on the other hand, are basically a combination of the first layer of the tetrahedral void with the second. A tetrahedral void has four coordination numbers. An octahedral vacuum, on the other hand, has a coordination number of six. WebAtomic Packing Factor (APF) tells you what percent of an object is made of atoms vs empty space. You can think of this as a volume density, or as an indication of how tightly-packed the atoms are. Calculating the atomic packing factor for a crystal is simple: for some repeating volume, calculate the volume of the atoms inside and divide by the total volume.
