Did you know?
WebThe face-centred cubic system has lattice points on the faces of the cube, that each gives exactly one-half contribution. In addition to the corner lattice points, giving a total of 4 lattice points per unit cell. For simple cubic, number of atoms per cell = 1. For bcc, number of atoms per cell = 2. For fcc, number of atoms per cell = 4. WebSo an FCC crystal can fill about 7% of it’s volume with interstitial atoms! Of course, if an FCC crystal was really filled with so many interstitial atoms, the lattice parameter would definitely distort and it would change to a different crystal structure. Interstitial Sites in BCC The BCC crystal has 12 tetrahedral sites and 6 octahedral sites.
