tiivistystekijä
Tiivistystekijä, often translated as compression factor or packing fraction, is a concept used in various scientific and engineering fields, particularly in materials science and physics, to describe how densely a substance or material occupies a given space. It quantifies the ratio of the volume occupied by the constituent particles or elements of a substance to the total volume of the space they are in.
In crystallography, tiivistystekijä refers to the proportion of the unit cell volume that is occupied by atoms.
Beyond crystalline solids, the term can also apply to the arrangement of particles in powders, colloids, or
