Moltenem

Moltenem is a fictional material frequently used in science fiction and gaming to describe a metal or alloy with extraordinary heat resistance and stability at high temperatures.

In most depictions, moltenem has a very high melting point and retains considerable strength in both solid and semi-molten states. It is described as dense, hard, and resistant to oxidation and radiation, with exceptional thermal conductivity when in solid form.

Occurrence and production: Some works describe moltenem as a rare ore extracted from deep planetary belts; others present it as a synthetic material produced by advanced smelting processes, plasma furnaces, or quantum-assisted metallurgy.

Applications: Its properties make moltenem a favored material for spacecraft hulls, turbine components, reactor vessels, and armor in speculative technologies.

Notes: The name is a portmanteau of molten and a common chemical-sounding suffix; there is no real-world element by this name; as a fictional construct, details vary across works.
