Close packing in crystals refers to space efficient arrangement of constituent particles in a crystal lattice. To understand this packing more clearly we have to assume all particles (atoms, molecules and ions) are of the same spherical solid shape.
The diagrammatic representation of three-dimensional arrangements of constituent particles in a crystal, where each particle is depicted as a point in space is known as a crystal lattice. In a crystal lattice, the atoms are very closely packed, leaving very little space between them. Close packing in solids in three dimensions is discussed below:
Nov 24, 2022 · Close-packed crystals must have close-packed, hexagonal 2D planes; the ways these planes are stacked is called “Stacking Order” and is the distinguishing characteristic between close-packed structures. Let’s explain stacking order by building some crystals.

Jan 30, 2023 · To maximize the efficiency of packing and minimize the volume of unfilled space, the spheres must be arranged as close as possible to each other. These arrangements are called closest packed structures. The packing of spheres can describe the solid structures of crystals.
How close-packed structures of spheres can be constructed: In a first layer the spheres are arranged in a hexagonal pattern, each sphere being surrounded by six others (A). Then a second layer with the same structure is added.
Close packing is the packing of spheres so as to occupy the minimum amount of space. The name close packed refers to the packing efficiency of 74.05 %. There are two types of close packing: hexagonal and cubic.
Aug 23, 2021 · Hexagonal Close-Packed (hcp) In a hexagonal close-packed structure, the third layer has the same arrangement of spheres as the first layer and covers all the tetrahedral holes. Since the structure repeats itself after every two layers, the stacking for hcp may be described as "a-b-a-b-a-b."
