Difference Between Isotropic and Anisotropic

Main difference

The main difference between isotropic and anisotropic is that isotropic is that the physical and chemical properties of the compound do not depend mainly on the direction and dimensions while anisotropic is that the chemical and physical properties of the compounds are mainly based on the directions. and dimensions. .

Isotropic vs Anisotropic

Isotropic compounds are direction independent, while anisotropic compounds are direction dependent. Isotropic properties are known for their constant and unvarying values; on the other hand; Anisotropic properties are variable. Isotropic compounds have only one type of refractive index; On the other hand, anisotropic compounds have more than one type of refractive index.

Features like optical activity, scattering, birefringence, and dichroism are present in isotropic compounds while features like optical activity, scattering, birefringence, dichroism are present in anisotropic compounds. Isotropic compounds have chemical bonds consisting of chemical reactions; on the other hand, anisotropic compounds have inconsistent chemical bonding in chemical reactions.

Isotropic compounds tend to appear dark in nature, while anisotropic compounds tend to appear bright in nature. The isotropic compound does not have the ability to pass sunlight through itself; on the other hand, the anisotropic compound has the ability to pass sunlight through itself.

The ability to conduct electricity in isotropic compounds is the same in all directions; on the other hand, the electric current conducting capacity in anisotropic compounds is different in different directions. The speed of light in isotropic compounds is the same in all directions; on the other hand, the speed of light in anisotropic compounds is different in different directions.

Isotropic compound applications are found in lenses while anisotropic compound applications are found in optical polarizers. The double refraction process is absent in isotropic compounds, while the refraction process is present in anisotropic compounds. The example of an isotropic substance is glass; On the other hand, the example of anisotropic compounds is wood.

The chemical, physical, and mechanical properties of isotropic compounds do not depend on the orientation of the crystals; on the other hand, the mechanical, chemical and physical properties of anisotropic compounds depend on the orientation of the crystals. The radiations of isotropic crystals have the same intensity in all directions; on the other hand, the radiations from anisotropic crystals do not have the same intensity in all directions.

The term “iso” means equal; on the contrary, the term “Aniso” means uneven. Isotopic compounds have cubic symmetry, while anisotropic compounds do not have cubic symmetry. Isotropic materials include amorphous substances like glasses, etc.; On the other hand, anisotropic materials are included in composite materials like wood etc.

What is isotropic?

The word isotropic means the same as it refers to physical, mechanical, and chemical properties that are the same in all directions. Isotropic properties do not depend on direction. They are the same in every way and are constant. The composition of isotopic crystals includes amorphous materials. Chemical bonding in isotropics generally refers to constant behavior.

Plant cell walls always considered as the isotropic material whose different properties and characteristics are the same in all directions. Cubic crystals often include substances such as sodium salts in the isotropes, and rock salts are also known for their unchanging properties. The hardness or solidity of cubic crystals remains the same whether the direction or conditions of the solids are.

Optical properties are generally not present in isotropic crystals, since it is the property that depends on the directions of the atomic arrangements. Examples of isotropics are glasses, lead wires, rock salt, sodium salt, etc.

What is anisotropic?

The term anisotropic means not the same and refers to chemical, physical, and mechanical properties that vary with change in position, location, and orientation. It means that all properties of anisotropic crystals depend mainly on orientation. They are variable in different directions. The composition of anisotropic crystals mainly includes composite materials.

The internal cytoplasm of living cells of organisms is mainly anisotropic, whose chemical, mechanical and physical properties continuously change with the change of direction and dimensions due to the presence of the intercellular organelles in the cytoplasm. Examples of anisotropics are wood, cubic crystals, plaster, etc.
