Lattice substitution refers to the process of replacing one type of atom or ion in a crystal lattice with another, which can alter the material's properties such as conductivity, magnetism, or color. This technique is widely used in materials science to engineer new materials with desired characteristics for various applications, including semiconductors and catalysts.

Process of replacing atoms

A crystal lattice is a highly ordered structure consisting of a repeating pattern of atoms, ions, or molecules in three-dimensional space, which gives rise to the unique properties of crystalline solids. Understanding the geometry and symmetry of crystal lattices is crucial for determining the material's physical properties, such as conductivity, strength, and optical characteristics.
