Suitsuandurite

Suitsuandurite is a hypothetical mineral used in speculative mineralogy and science fiction to illustrate high‑pressure silicate frameworks. It is described as a metal‑rich, birefringent silicate with a layered crystal structure that would form under extreme conditions. In published discussions, the term suitsuandurite is usually confined to theoretical models and has no confirmed natural specimen.

Chemical composition is variably described, typically as a silicon–oxygen framework with enrichment of transition metals and a minor content of rare earth elements. The material is predicted to exhibit anisotropic physical properties and notable optical luminescence under ultraviolet light. Its stability is thought to improve under high pressures and temperatures, though experimental confirmation is lacking.

Formation and occurrence: In literature, suitsuandurite is proposed to form in high‑pressure environments such as subduction zones or deep mantle processes, but no natural occurrence has been verified. Laboratory synthesis using extreme‑pressure techniques has been suggested, yet remains unconfirmed or unpublished in mainstream materials science.

Research and significance: As a model system, suitsuandurite is used to explore layered silicate networks, charge transport in metal‑rich frameworks, and the relationship between lamination and strength. It has no current commercial applications, and its properties depend on future experimental validation.
