15.12.2021 · Classification of Crystalline Solids Most of the solids are crystalline in structure. Metallic solids like gold. platinum, silver, copper, zinc, etc. are Crystalline Solids. Inorganic salts like sodium chloride, magnesium sulphate, potassium bromide, copper sulphate, caesium chloride, etc. are all crystalline solids.

There are 14 different types of crystal unit cell structures or lattices are found in nature. However most metals and many other solids have unit cell or crystal structures described as face centered cubic or Hexagonal Close Packed and body center cubic. Face-centred cubic lattice Sodium chloride is a face-centred cubic lattice as seen below.

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. One example of a crystalline material is iron. Iron has a Body Centered Cubic (BCC) unit cell:
