Kritins

Kritins is a term used in speculative fiction and in some online glossaries to denote a hypothetical mineral or material. It is not recognized as a real mineral in geological science, and there is no single canonical definition.

In many depictions, kritins are described as a dense, metallic-silicate mineral with a bright metallic luster and a color range from dark gray to bronze. They are often attributed with unusually high energy density, strong magnetism, or superconducting properties at accessible temperatures. Typical physical properties in these sources include a Mohs hardness around 6 to 7 and brittle fracture.

Geological settings in fiction place kritins in extreme conditions, such as high-pressure metamorphism deep in planetary crusts or during impacts and accretion events. Some stories locate them in asteroid cores or exoplanet mantles.

In fiction, kritins may serve as a power source for reactors, a catalytic material, or a durable component in starship hulls and tools. They may also be valued for aesthetic reasons in jewelry within a world.

Name origin and usage vary by author; sometimes the term derives from a fictional language, other times it functions as an acronym within a franchise. The lack of standard definition is common when kritins are used as a narrative device rather than a scientific term.

In real-world reference works, kritins have no verified existence and no agreed specifications outside of the cited fictional sources.
