Usage

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.
