In a face centred cubic of a and b
WebBody-centered cubic (bcc) and face-centered cubic (fcc) structures are important lattices because they appear in many solids, e.g., Ar, Ag, and Ce (fcc) and Ba, Cr, Fe, K, and Li (bcc). Both structures are modified from the simple cubic system and are shown here with the locations of the atoms. The bcc structure has eight atoms at the corners ...
