deuteriumia

Deuteriumia is a fictional chemical element used in speculative science and science fiction worldbuilding. Named for a suggested relationship to deuterium, it is described as a heavy, dense metal with unusual isotopes and a high atomic mass.

In most depictions, deuteriumia is a superheavy element that does not occur naturally on Earth. It is produced only in exotic settings, such as particle accelerators in the story universe or in the interiors of certain fictional stars, and remains scarce outside controlled environments.

Physically, it is depicted as a ductile, corrosion-resistant metal with a high melting point and density exceeding that of typical metals. It is said to form stable deuteride compounds with hydrogen isotopes, and can support unusual oxidation states under extreme pressures.

Applications in fiction include energy storage and transfer, neutron-mapping materials, fusion reactor components, and specialized electronics. Some worldbuilding traditions posit that deuteriumia-based alloys exhibit superconductivity at relatively accessible cryogenic temperatures, making them attractive for advanced technologies.

Synthesis and handling are tightly controlled in the fictional setting, since certain isotopes of deuteriumia are described as mildly radioactive and potentially hazardous if mishandled. Ethical and regulatory frameworks typically govern its extraction, transport, and use.

Deuteriumia remains a speculative construct and is not recognized by real-world chemistry.
