Packing factor is the fraction of the volume of a unit cell that is occupied by "hard sphere" atoms or ions. It is the sum of the sphere volumes of all atoms within a unit cell (assuming the atomic hard-sphere model) divided by the unit cell volume. It is dimensionless and always le...

Packing of atoms in the unit cell. Atoms have a different arrangement in the element which can be a simple cubic cell, body-centered cubic cell or face-centered cubic cell. Each arrangement has a different atomic packing fraction ...
Determine the planar density and packing fraction for BCC lithium in the (100), (110), and (111) planes. Which, if any, of these planes is close packed? Draw the planes (100) and (110) in BCC unit cell and calculate their planar densities. Calculate the Pla...
The fraction of α2 can be determined in terms of subtraction of the structure less line shape from the observed spectra at various ∆Ts. As results, the maximum α2 fraction was determined to be 62% at Tc = 150 ◦C, where crystallization takes more than 30 days. Furthermore, the ...
