Metallidels
Metallidels is a term encountered in speculative materials science and in some fictional contexts to denote a proposed class of metallic nanostructures. It is not part of established mineralogical or metallurgical taxonomies, and there is no widely accepted formal definition in peer‑reviewed literature.
In discussions that use the term, metallidels are described as nanoscale metallic clusters or particles with
Natural occurrence is not established; proposed formation paths include laboratory synthesis through chemical reduction or electrochemical
Research status is largely theoretical or exploratory. Some studies on metal clusters and nanoparticles explore related
