Formation of Titanium Powder by Potassium Reduction of Titanium Salts.
NTIS: PB 88-114467 :20 pages
This report describes the investigation of a process to produce titanium powder directly from titanium salts. If successful, such a process could lower the cost and increase the use of titanium. In this study, k2tif6, k2tif5, and tif3 were reduced with potassium in the temperature range of 650 deg to 750 deg c. Under certain conditions, titanium powder 1.6 to 3.3 Um in size was produced. After leaching the product with a 0.1M hcl solution, powder with impurities as low as 0.04 pct potassium and 0.28 pct fluorine were obtained. However, oxygen levels of over 1 pct and the frequent formation of insoluble byproducts demonstrate the need for further research to make the powder suitable for powder metallurgy applications.
