Which of the following lattices has the highest packing efficiency (i) simple cubic (ii) bodycentred cubic and (iii) hexagonal close-packed lattice ? |
|
Answer» Solution :(i) Simple CUBIC : 52% PACKING efficiency (II) Body-centred cubic : 68% packing efficiency (iii) Hexagonal close packing : 74% packing efficiency. Hence, Hexagonal close-packed structure is maximum efficient. |
