However, because of the high cost of extraction and processing, titanium use has been less than anticipated. The present paper addresses the question of reducing the cost of titanium production either by replacing the present Hunter or Kroll extraction processes by a more costeffective method, or in a quantum leap by going directly from the ore, or beneficiated ore, to a prealloyed powder ...

· 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. That means that you have to use an .
