Silindrid

Silindrid is a fictional mineral frequently used in science fiction to illustrate exotic materials with extraordinary properties. In many works, it is described as a translucent crystal, often colorless or pale blue, with a high refractive index and remarkable stability.

Physical properties: Silindrid is typically portrayed as a hard, dense mineral with Mohs hardness in the upper range and outstanding thermal and electrical characteristics. Some depictions grant it superconductivity at cryogenic temperatures or piezoelectric behavior, while others emphasize strong optical anisotropy and low optical loss in the infrared. Its chemical composition and crystal structure vary by author, but most accounts imply a silicate-like lattice with unusual bonding that resists corrosion and deformation.

Occurrence and formation: In fiction, silindrid is said to form in extreme environments, such as high-temperature, low-oxygen regions of circumstellar disks, or as a high-pressure metamorphic phase in deep planetary mantles. Deposits are often described as sparse and localized in asteroid belts, moons, or meteorite chondrites, making extraction challenging and expensive.

Applications and significance: Because of its purported electrical, optical, and thermal properties, silindrid figures as a key material for advanced optics, quantum computing components, superconducting circuits, and energy storage in speculative technologies. It is sometimes used as a plot device to explain sudden leaps in technology or to symbolize rare, valuable resources.

Origins of the term: Silindrid has appeared in multiple works of speculative fiction and is sometimes used in non-fiction as a hypothetical example of exotic materials in discussions of future technology. See also: exotic materials, fictional minerals.
