Titanium and titanium alloys

Abstract

A titanium powder or alloy powder produced by introducing a TiCl 4 vapor into a continuum or flowing stream of sodium metal at a velocity not less than sonic velocity of the vapor wherein the sodium is present in an amount greater than stoichiometric sufficient to maintain substantially all the reaction products below the sintering temperature thereof and wherein said Ti powder has a packing fraction in the range of from about 4% to about 11%. The powders without fines have a particle diameter in the range of from about 3.3 to about 1.3 microns based on a calculated size of a sphere from a BET surface area in the range of from about 0.4 to about 1.0 m 2 /g.

         49 . A titanium powder produced by introducing a TiCl 4  vapor into a flowing stream of sodium alkali metal at a velocity not less than sonic velocity of the vapor wherein the sodium is present in an amount greater than stoichiometric sufficient to maintain substantially all the reaction products below the sintering temperature thereof and, wherein said Ti powder has a packing fraction in the range of from about 4% to about 11%.

         84 . A titanium or titanium alloy powder produced by the method of submerging a titanium halide vapor or mixture of halide vapors in a continuum of liquid sodium metal thereof present in sufficient quantities to maintain the titanium or titanium alloy below the sintering temperatures thereof wherein the powder is titanium without fines and has a particle diameter in the range of from about 3.3 to about 1.3 microns based on a calculated size of a sphere from a BET surface area in the range of from about 0.4 to about 1.0 m 2 /g, and, wherein said Ti powder has a packing fraction in the range of from about 4% to about 11%.
