| Abstract Scope |
A direct production process for TiH2 powder with oxygen concentration below 0.25 mass% from TiO2 was investigated via a single-step reduction. The reduction was performed using Mg in a MgCl2 – KCl molten salt at 973 K under an Ar – 10 % H2 mixed gas atmosphere. The oxygen concentration in the resulting TiH2 powder decreased with decreasing TiO2 particle size (45 – 300 μm). When TiO2 powder with a particle size of 45 – 75 μm, composed of agglomerated nanosized primary particles, was used as feedstock after wet-sieving, the oxygen concentration was reduced to 0.209 mass%. These results demonstrate the feasibility of directly producing low-oxygen TiH2 powder from TiO2 via a single-step reduction using Mg metal at 973 K under an Ar – 10 % H2 mixed gas atmosphere. |
