To answer this question we must look at the HCP itself. We know it is a Hexagonal close packet (HCP) With a CN=12 and common elements are Ti, Mg, Cd etc.Now we have the backup theory, let's answer the question.
APF (Atomic packing factor) will equal Vs/Vc
where Vs is volume of the atoms contained within the unit cell. Vc
being the volume of total unit cell. Now we look at the structure HCP:
Imagine a hexagonal with 6 equilateral triangles contained.
Firstly what is Vs? Easy: (volume or sphere?) =
4/3(pie)R^3 x 6 (x6 because of 6 spheres per unit cell, remember? HCP has 6 atoms contained)
Dissect one equilateral triangle off to work out it's area. The area of this equilateral triangle? Now the side lengths will be a (any value) with 60 degree angles at each edge (total of 180 degrees) therefore the are will be A=a
x a x 1/2 x sin(60) =
(Sqrt(3) x (a^2)) / 4
Now multiply the area of the single triangle by 6 (remember, 6 triangles).
Total Area of base of hexagonal =
(Sqrt(3) x (3) x a^2) / 2
Now remember the formula relating a with R =>
a =
2R
Sub R into our base area formula, therefore =
6 x Sqrt(3) x R^2 (excluding working out)
Now recall the c/a ratio of HCP? c/a=1.63
Hence c =
1.63 x a > Now sub R (a =
2R...)
c =
3.26 x R
Now recall the question? APF? Therefore look back at Vc
/Vs, what are we missing? Vc,
now Vc
=
c x base...
Vc
=
3.26 x R x 10.392 x R^2 =
33.878 x R^3
therefore
APF =
Vs (recall from top working out) / Vc
=
(8 x (pie) x R^3) / 33.878 x R^3
Vc
=
0.74 ( cancel the R^3)
Easy eh? haha
