WebAug 27, 2024 · A BCC has 6 octahedral holes and 12 tetrahedral holes. At each face of the bcc, there is one octahedral hole. There is also an octahedral hole on each edge. We divide the holes found on the faces by 2 as they lay between two unit cells, and we divide the holes found on the edges by 4 because they likewise lay between 4 unit cells. WebThe bcc arrangement does not allow the atoms to pack together as closely as the fcc or hcp arrangements. The bcc structure is often the high temperature form of metals that are close-packed at lower temperatures. The volume of atoms in a cell per the total volume of a cell is called the packing factor. The bcc unit cell has a packing factor of ...

I hope this will be the same for the case with calculations for ibrav=3, with BCC primitive cell with one atom per cell. WebSep 7, 2024 · Answer and Explanation: In the case of Body-Centered Cubic (BCC) unit cell, the relationship between the edge length (l) and the radius (r) of the atom happens to be l=4√3r l = 4 3 r . Volume of unit cell for BCC = l3= (4√3r)3=643√3r3 l 3 = ( 4 3 r ) 3 = 64 3 3 r 3 . What is the volume of void in FCC? Void space in fcc unit cell is 26% .
