Preparing low-oxygen titanium powder by calcium reductant from titanium hydride
In a previous study, we prepared a low-oxygen titanium powder from titanium scrap through Hydrogenation-Dehydrogenation and deoxidation in a solid-state (DOSS) process with calcium. In this study, an advanced deoxidation in a solid-state process applied titanium hydride as a raw material is proposed to shorten the time of the previous DOSS process. Compared to the previous DOSS process, the total process time was shortened, and the same oxygen reduction rate was obtained. In addition, it was confirmed that the low-oxygen titanium powder prepared this by advanced DOSS process has a superior oxidation resistance than the titanium powder obtained by the previous study.
