Steradiante

Steradiante is a fictional mineral described in speculative geology and science fiction narratives. It is presented as a silicate-rich material with distinctive energy-storage and luminescent properties, capable of emitting light after stimulation and of holding charge within its crystal lattice.

Physical properties typically attributed to steradiante include a tetragonal crystal system, a vitreous to greasy luster, and a hardness around 6 on the Mohs scale. Color ranges from colorless to pale blue. The mineral is said to exhibit photoluminescence, emitting light after exposure to ultraviolet light or electric fields. Its lattice is described as trapping charge carriers, enabling rapid light release when stimulated.

Occurrence and geology within fictional settings place steradiante in hydrothermal veins within basaltic rocks, often associated with ultramafic host formations. In many narratives, deposits are located in the Serpentine Belt of the planet Novaris or in terrestrial analogs used for storytelling about future mining frontiers.

Extraction and processing methods are described as open-pit or underground mining, followed by annealing and dopant treatments to activate luminescent centers. Stabilization often requires controlled cooling and protective atmospheres to preserve the material’s luminescent and energetic properties.

Applications commonly explored in fiction include energy storage for photonic devices, lightweight radiation shielding for spacecraft, and luminescent wiring in advanced circuits. The concept of steradiante serves as a narrative device to explore interactions between minerals, energy, and light in future technologies.

Name and history: the term steradiante is framed as deriving from star-related radiance. In fictional accounts, it was first described by mineralogist Arin Sol in 2142. See also: steradian, luminescence, photonic materials.
