Only one carbide of Ti is known to exist, 5-8 TiC (melting point 3340~ "TIC" is generally considered to have a considerable deficit of carbon and thus may vary continuously from Til.sC to TiC.

Smelting Temperature - an overview | ScienceDirect Topics

Therefore, a very high temperature (900–1000 C) is required to keep the bath in molten phase, which is a high energy–consuming process. Ionic liquids (nonconventional organic solvents, electrolytes, and molten salts) exhibit low melting points and could dramatically reduce the necessary smelting temperature for aluminum production ( Zhang et al., 2003 ).
