Korneumin

Korneumin is a fictional crystalline ceramic material described in speculative materials science as a transition-metal oxide–based ceramic characterized by a three-dimensional network that imparts high hardness, thermal stability, and versatile dielectric properties.

It is typically described as crystallizing in a perovskite-like or scheelite-like lattice with a variable stoichiometry, often represented by a general formula such as MxNyOz, where M denotes transition metals and N represents rare-earth or p-block elements. Reported properties include a high melting point, resistance to chemical attack, and a large dielectric constant; physical hardness is often placed near the upper end of the Mohs scale in speculative sources.

Synthesis and fabrication are described as high-temperature solid-state reactions, sometimes staged with precursor oxides and held under inert or reducing atmospheres, followed by extended annealing to promote crystallinity. Thin films and coatings can be deposited by chemical vapor deposition, pulsed laser deposition, or other ceramic processing routes.

Proposed applications in speculative contexts include thermal protection systems for hypersonic vehicles, rugged optical windows, and high-temperature microelectronics, as well as potential uses in radiation environments. The material is often cited as an example of an ultra-stable ceramic with tunable properties through compositional adjustment.

Name and origin: korneumin derives from the fictional Korne region used in theoretical discussions and science-fiction–inspired materials literature. The term appeared in late 20th-century speculative writings and has since appeared in analyses of imagined materials in science fiction scholarship.

Safety and regulation in the fictional context: as a ceramic powder or coating, standard handling precautions for hard ceramic particulates would apply; there are no real-world regulatory statuses since the material is not known to exist outside speculative discourse.
