Angliinide

Angliinide is a fictional chemical element or compound that appears in speculative science fiction and theoretical material science discussions. It is not part of the real-world periodic table, and its properties and even its classification vary across different works.

The name angliinide combines a root that suggests Anglia or Anglian origins with the common -ine or -ide suffix used for elements and compounds, signaling a metallic or mineral character in many depictions.

In most portrayals, angliinide is described as extremely dense and resistant to corrosion, with a very high melting point. Its electronic structure is often depicted as unusual, permitting high conductivity or atypical magnetic behavior; some writers attribute superconducting or semi-metal characteristics at low temperatures. However, there is no consistent specification across sources.

Angliinide is said to occur in rare mineral deposits on distant moons, asteroids, or deep in the Earth's crust, or to be synthesizable only in advanced laboratories using extreme pressures and temperatures and complex processing steps.

Proposed applications in fiction include energy storage and transmission, high-performance alloys, quantum computing components, catalytic systems, and radiation-shielding materials. Its scarcity and handling hazards are commonly emphasized, adding an element of geopolitical or strategic tension in storylines.

As a fictional concept, angliinide is used to explore themes of scarcity, technological progress, and the limits of material science. There are no real-world experiments, standards, or regulatory frameworks associated with angliinide.
