A homogenous material is a material that consists of uniform composition throughout. It is a material that is characterized by its inability to be separated mechanically into different materials.
A characteristic of homogenous material is that it is made up of only one compound or element. There are several types of common homogenous materials, which include some types of ceramics, metals, plastics, alloys, paper, boards, resins or coatings.
While these elements cannot be mechanically separated, the definition of "mechanically separated" can differ in principle than in practice. For instance, in principle, mechanically separated actually means that material can be separated by unscrewing, cutting, crushing or grinding.
