What is meant by crystallographic?
crystallography, branch of science that deals with discerning the arrangement and bonding of atoms in crystalline solids and with the geometric structure of crystal lattices. Modern crystallography is largely based on the analysis of the diffraction of X-rays by crystals acting as optical gratings.
How do you find the lattice structure?
Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound. In simple ionic structures, we usually find the anions, which are normally larger than the cations, arranged in a closest-packed array.
What are the four types of crystal structure?
There are four types of crystals: (1) ionic , (2)metallic , (3) covalent network, and (4) molecular .
What are the four main types of lattice structures?
Important lattice structures are the face-centered cubic (fcc), the body-centered cubic (bcc), and the hexagonal closest packed (hcp).
What is the use of lattice structure?
Lattice structure is an attractive material for many design applications (aerospace, biological engineering, mechanical engineering, etc.) because of the excellent properties including the light-weighting, high specific strength and stiffness, dissipate heat, and so on.
What are the types of lattice structure?

What are the types of crystal structures?
Each crystal lattice is defined by a crystal system. In three-dimensions, there are seven crystal systems: triclinic, monoclinic, orthorhombic, hexagonal, rhombohedral, tetragonal, and cubic. These collection of systems are called the Bravais lattices.
