Liialdust

Liialdust is a fictional mineral name used in speculative science and science fiction to denote a fine, lithium-rich silicate dust. It is not a recognized mineral species in real-world geology or mineralogy. In narrative and thought-experiment contexts, liialdust is described as a low-density particulate material with high surface area and a propensity to absorb moisture and atmospheric gases due to its lithium content.

In proposed compositions, liialdust is imagined as a lithium-aluminum silicate or glassy lithium-rich phase, often with traces of other alkali metals and refractory oxides. Particle sizes are typically micrometric or submicrometric, forming as a dusty aerosol in high-temperature environments or as condensed grains from rapid quenching of silicate melts.

Formation and distribution are fictional: liialdust is said to form around lithium-rich magmas, volcanic outgassing, or in laboratory condensates where melts are cooled rapidly. In science-fiction settings, it may accumulate in planetary regoliths or industrial exhaust streams, where its reactivity and dust behavior have to be managed.

Proposed properties and uses are speculative. The material is described as having high energy density potential per unit mass due to lithium content, suggesting possible roles in theoretical energy storage or catalytic processes. However, its high hygroscopicity and chemical reactivity with water pose health and safety concerns, including ignition risk for fine aluminum-lithium mixes and respiratory hazards for inhalable particles.

Because liialdust is fictional, there are no formal classifications or regulations. Related concepts include lithium-containing silicates, silicate dusts, and nanoscale lithium materials.
