    Titanium can''t be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, 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. That means that you have to use an alternative reducing agent.
