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.
