Kliaside

Kliaside is a fictional mineral name used in speculative mineralogy and science fiction to illustrate properties of a hypothetical silicate phase. It is described in various sources as a layered, sheet-bearing mineral with a composition that could support unusual physical behaviors under extreme conditions. The name is commonly attributed to a fictional origin, sometimes linked to a place called Klia, and it follows standard mineral-naming conventions by ending with the suffix -ide.

In the fictional descriptions, kliaside is said to have a phyllosilicate-like structure, with silicate tetrahedra arranged in sheets and interconnected by larger cations. Reported physical properties vary by author, but typical depictions place its hardness around 5 to 6 on the Mohs scale and its density near 3.0 to 3.3 g/cm3. The color range is usually described as pale green to blue or violet, and some sources note optical anisotropy with notable birefringence.

Occurrence and synthesis within the fictional framework place kliaside in high-temperature hydrothermal systems or as a high-pressure metamorphic phase in subduction zones. No verified natural specimens exist in real geological literature, reflecting its status as a construct of imagination. When described in theoretical discussions, kliaside is often proposed to be producible synthetically through hydrothermal methods from typical silicate constituents such as potassium, aluminum, silicon oxides, at temperatures of several hundred degrees Celsius under modest pressures.

Uses in real-world technology are not applicable due to its fictional status. In speculative contexts, writers imagine potential applications in electronics, luminescent devices, or as a model material for studying layered silicates, though no experimental evidence supports these claims.
