• Description:
  The U.S. Bureau of Mines continued research on the preparation of titanium nitride powder for potential use as a substitute for imported tungsten used in metal cutting tools and wear-resistant applications. Major emphasis was directed toward improving the purity of the powder produced by vapor-phase reaction of titanium tetrachloride with magnesium in the presence of nitrogen or anhydrous ammonia at 1,000 deg c. Modifications were made in powder collection, handling, and purification procedures that significantly reduced the oxygen content of the product from >5 wt pct to <1 wt pct. Powder samples contained oxygen contents as low as 0.23 Wt pct and exhibited a median particle size of 0.28 Um. [Description provided by NIOSH]
