摘要：

The production of metallic titanium (Ti) through the reduction of titanium oxide (TiO2) by aluminothermic reduction technique, using hydrogen plasma to trigger the reaction has been investigated. Titanium oxide and aluminum powders were previously processed by high energy grinding during 4, 6 and 10h. Also, a thermal analysis study was done to know the temperature for the aluminothermic process in TiO2-Al mixtures. The product obtained was characterized by X-ray diffraction and scanning electron microscopy and Rietveld method was used in the microstructure refinement. The results show that is possible to obtain a titanium rich compound through the hollow cathode plasma technique.
