2020-8-21  Titanium Extraction. Titanium cannot be extracted by reducing the ore using carbon as a cheap reducing agent, like with iron. The problem is that titanium forms a carbide, \(\ce{TiC}\), if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle.
