eritilemez

eritilemez is a Turkish adjective meaning "unable to be melted." It derives from eritmek, the verb "to melt," combined with the negative suffix -ilemez. In Turkish, the term can describe substances that do not melt under ordinary heating, or more broadly, materials with very high melting points.

In science and engineering contexts the word is used descriptively rather than as a precise technical term. Because melting depends on temperature, pressure, and chemical state, no material is truly unmeltable in all conditions; instead, 'eritilemez' conveys a relative property—useful when comparing materials that resist melting at practical temperatures.

Common contexts include discussions of refractory materials. Materials often labelled as 'eritilemez' include certain refractory metals and ceramics, such as tungsten and other very high-melting-point alloys, as well as oxide ceramics like alumina and silicon carbide. These materials find applications in high-temperature environments, such as furnace components, crucibles, or thermal barriers, where resistance to melting is important.
