Unobtainium is a term coined by engineers to describe materials that do not exist. When you find that the material properties required for a particular function cannot be met by an material known to modern science, the material that you need is unobtainium. Examples include:
- Metals with impossibly high melting points.
- Structural materials with impossibly high tensile strength.
- Fuels or explosives with impossibly high energy density.
This term has appeared at least once in science fiction, describing a material with impossible properties. May science fiction materials actually fit this description, though.
