WebThe bcc unit cell has a packing factor of 0.68. Some of the materials that have a bcc structure include lithium, sodium, potassium, chromium, barium, vanadium, alpha-iron and tungsten. Metals which have a bcc structure are usually harder and less malleable than close-packed metals such as gold. WebThe body-centered cubic unit cell is the simplest repeating unit in a body-centered cubic structure. Once again, there are eight identical particles on the eight corners of the unit cell. However, this time there is a ninth identical particle in the center of the body of the unit cell.
WebBody-centered cubic unit cell: In body-centered cubic unit cell, the number of atoms in a unit cell, z is equal to two. Hence, density is given as: D e n s i t y o f u n i t c e l l = 2 × M a 3 × N A 3. Face-centered cubic unit cell: In face-centered cubic unit cell, the number of atoms in a unit cell, z is equal to four.
