What isanisotropic

Anisotropy refers to the property of having different values of properties when measured along axes in different directions.

This property is particularly evident in single crystals of solid elements or compounds where the arrangement of atoms or ions is in a regular lattice. In contrast, liquids and gases have a random distribution of particles and hence are rarely anisotropic.

One example of anisotropy is birefringence – the difference in the speed of light along different axes of crystals of the mineral calcite. This property applies to several materials and is defined by values measured along different axes when determining a material’s mechanical and physical properties such as its refractive index, tensile strength, and absorptivity.

Anisotropy occurs in crystals, liquid crystals and, less frequently, in liquids. For instance, consider the primitive cubic crystal lattice structure where all atoms are of the same element. The distances A-B, A-C, and A-D in this structure are all different. When viewed along different axes, this leads to different physical and mechanical properties, like electrical and thermal conductivity and light polarization.
