Abstract
Disclosed is a deoxidation apparatus for preparing low-oxygen titanium powders. The deoxidation apparatus includes a lower container having an open upper portion and storing an deoxidizer representing an oxygen degree higher than an oxygen degree of titanium and a melting temperature lower than a melting temperature of titanium, and an upper container coupled with the lower container on the lower container and storing titanium base powders. The upper container is provided at a lower surface thereof with a sieve, and allows the deoxidizer, which is evaporated due to heating, to make contact with the titanium base powders so that the titanium base powders are deoxidized.
