Abstract
Process for deoxidizing refractory metals such as titanium which contain less than about one percent oxygen. The process described includes heating a liquid metal deoxidant contained in a liquid metal carrier to treat the oxidized metal. After removing the carrier and cooling, the metal is leached to result in a treated metal with lower residual oxygen. In a preferred embodiment, titanium alloy powders are deoxidized with calcium in a sodium carrier.
