Abstract

This study developed a new process for the economical deoxidation of titanium powder in order to solve the problems associated with the previous deoxidation process. In the experiment, titanium powder with an irregular particle shape was used as the raw material with an oxygen concentration of 2100 ppm. The amount of Ca was reduced by 50% as compared to that used in a previous work and placed in an improved apparatus at a weight ratio of 2:1 (Ti:Ca). This modified deoxidation process decreased the oxygen concentration of the titanium powder to 805 ppm at 1273 K, leading to a ∼61.7% reduction of oxygen compared to the raw titanium powder. Low-oxygen irregular titanium powder can be produced at a low cost and high efficiency by applying a non-contact deoxidation process using Ca vapor.
