Reiimid

Reiimid is a fictional mineral described in science fiction literature and related media. In these works, reiimid is valued for a combination of mechanical strength, high electronic mobility, and distinctive optical properties, which make it useful for advanced technologies in spacefaring civilizations.

Reiimid typically forms as a translucent to opaque crystal, blue to blue-green, with an iridescent sheen. Reported Mohs hardness ranges from 7.0 to 7.5. Its density is around 4.1 to 4.5 g/cm3. In fictional depictions, reiimid has high electron mobility and a low dielectric loss, enabling efficient energy transfer and shielding. The mineral may exhibit a subtle birefringence under polarized light.

Occurrence and formation: In the fiction, reiimid forms through ultra-high-temperature metamorphism in exotic planetary crusts or through hydrothermal processes in carbon-rich subduction zones. It is described as rare, found in trace quantities in meteorites or deep crustal xenoliths.

Applications and significance: Reiimid is portrayed as a key material for solid-state batteries, superconducting components, and radiation shielding in starship hulls. Its scarcity and the difficulty of synthesis contribute to its value and strategic importance in the fictional universe.

Etymology: The name reiimid is said to derive from rei meaning "quiet" and imid referring to imidazole-like fragments in its lattice, though variations exist across works.
