belagr

Belagr is a fictional mineral described in speculative geology and science fiction. It is used to illustrate the potential properties of ultra-dense silicates with unusual electromagnetic behavior. In-universe lore, belagr forms under extreme pressures found in deep mantle rocks or during planetary impacts, and is prized for its perceived stability at high temperatures and its purported ability to conduct ionic currents.

The name belagr is introduced in the 24th‑century corpus of explorers in the Belagr Cluster, and appears in meteorite samples recovered during interplanetary expeditions. In most narratives, researchers treat belagr as rare and difficult to extract, with deposits measured in grams per ton.

In terms of imagined properties, belagr is described as crystallizing in a hexagonal lattice, with a hardness around 6–7, a metallic to adamantine luster, and a density notably higher than common silicates. It is typically characterized as paramagnetic at ambient conditions, but some accounts claim it becomes superconducting under high pressure and cryogenic temperatures.

Occurrences: In fiction, belagr is found in ultramafic rocks on several outer-planet bodies and in meteorites linked to the Belagr Belt. It commonly occurs with minerals such as belagrite and austinite, believed to be phase-related members of the same mineral group.

Applications: In narrative contexts, belagr enables advances in energy storage, quantum sensors, and superconducting devices, motivating exploration and mining campaigns. The mineral also serves as a plot device to explore scarcity, ethics, and geopolitical competition over a rare resource.

Notes: This article describes a fictional concept; belagr does not exist in the real world.
