Raskasmetallia

Raskasmetallia is a fictional chemical element and alloy used in science fiction and speculative material science. It is not a real substance, and its properties vary between works, but it is typically presented as a dense, corrosion-resistant metal with exceptional strength.

In common depictions, raskasmetallia has a density around 19–21 g/cm3 and a melting point well above 1800°C, with a crystal structure that provides both high hardness and ductility. Electrical and thermal conductivities are described as high, comparable to or exceeding those of copper and aluminum alloys.

Extraction and production are described as challenging processes, often requiring controlled vacuum environments, specialized reduction methods, or synthesis in advanced reactors. Natural occurrence is treated as rare in most stories, with primary sources suggested to be meteorite deposits, asteroid belts, or bespoke fabrication in space-based facilities.

Applications in fiction include armor plating, hulls for spacecraft, radiation shielding, and components for nuclear or particle-physics experiments. The material may be alloyed with other elements to tailor properties, or used in composite forms for enhanced toughness.

Raskasmetallia is a fictional construct and is used to explore themes of material limits, resource scarcity, and advanced manufacturing. Real-world researchers treat it as a hypothetical example rather than a real element, and references to it are limited to literary or theoretical contexts.
