Metallosade

Metallosade is a coined term that has appeared in limited online glossaries and some science fiction or speculative writing to describe a hypothetical metal-rich solid phase associated with metallurgical processes. It is not a term with formal status in peer-reviewed mineralogy, materials science, or geology, and there is no universally accepted definition.

In informal or fictional usage, metallosade is sometimes depicted as a composite material consisting of metal-rich grains embedded in a surrounding phase such as glass, sulfide, or oxide. Some writers and hobbyists use the concept to describe residues or byproducts generated during metal smelting or alloy processing, suggesting that metallosade could concentrate metals or exhibit distinctive microstructures. Because the term lacks formal standardization, its described composition, structure, and properties vary across sources.

Characteristics attributed to metallosade in non-scholarly contexts are typically speculative and not backed by experimental data. Descriptions often emphasize metallic luster, high density, and variable magnetic or electrical behavior depending on the assumed metal content. In most formal contexts, materials with similar appearance or function are discussed under established categories such as slag, oxide minerals, sulfide minerals, or metallic glasses rather than under a term like metallosade.
