Usage
[edit]Used with User:Just granpa/Atomic volume (Alternate)
Returns the Atomic packing factor for a given crystal structure.
Syntax: {{User:Just granpa/Atomic packing factor|crystal structure|a=|b=|c=|alpha=|beta=|gamma=}}
a, b, c, alpha, beta, and gamma are optional lattice parameters.
Structure APF liquid 0.8*0.74=0.592 amorphous 0.9*0.74=0.666 fcc 0.74 hcp 0.74 dhcp 0.74 bcc 0.68 pc 0.52 sc 0.52 dc 0.34 hex 0.6 orth 0.547 tetr 0.6 rho 0.6 mon 0.6 default {{{1}}}
The packing factors in yellow are placeholders which are necessary for User:Just granpa/Atomic volume (Alternate) and User:Just granpa/Atomic radii to work properly.
It is my hope that someday they can be replaced with a precise equation.
