WebThe structure formed is also called cubic closed packed (ccp) or face-centred packed cubic structure (fcc). For Example metals like copper and iron crystallize in the structure. The coordination number in both cases will be 12 as each sphere in the structure is in direct contact with 12 other spheres. WebIn hexagonal close packing and cubic close packing, a sphere has the coordination number 12. In hexagonal close packing and cubic close packing 74% of the space in the crystal … ctf-web工具

WebThe number of tetrahedral voids is formed twice as the number of octahedral voids while close packing of atoms in ccp and hcp structures. Thus, if number of close packed spheres is equal to ‘N’. Therefore, number of octahedral voids formed = N. And, the number of tetrahedral voids formed = 2N.
