| 20120070578 | METHOD FOR PRODUCING TITANIUM METAL - Disclosed is a method for producing titanium metal, which comprises: (a) a step in which a mixed gas is formed by supplying titanium tetrachloride and magnesium into a mixing space that is held at an absolute pressure of 50-500 kPa and at a temperature not less than 1700° C.; (b) a step in which the mixed gas is introduced into a deposition space; (c) a step in which titanium metal is deposited and grown on a substrate for deposition; and (d) a step in which the mixed gas after the step (c) is discharged. In this connection, the deposition space has an absolute pressure of 50-500 kPa, the substrate for deposition is arranged in the deposition space, and at least a part of the substrate for deposition is held within the temperature range of 715-1500° C. | 03-22-2012 |
| 20110277590 | Method For Producing Metal Nanopowders By Decomposition Of Metal Carbonyl Using An Induction Plasma Torch - A process for synthesizing metal nanopowders by introducing metal carbonyl into an induction plasma torch. By taking advantage of the much lower dissolution temperature of carbonyl as opposed to the high melting temperature of conventional metal powder feeds less torch power is required. Moreover, in contrast to current powder production techniques utilizing electrode based plasma torches, the induction plasma torch does not introduce contaminants into the nanopowder. | 11-17-2011 |
| 20090260481 | METHOD FOR PRODUCING TITANIUM METAL - A process and apparatus for producing titanium metal is described herein. The process comprises generating an RF thermal plasma discharge using a plasma torch provided with an RF coil; reducing titanium tetrachloride to a titanium metal by supplying titanium tetrachloride and magnesium into the RF thermal plasma discharge; and collecting or depositing the titanium metal at a temperature not lower than the boiling point of magnesium chloride and not higher than the boiling point of the titanium metal. | 10-22-2009 |
| 20090243168 | APPARATUS FOR PLASMA SYNTHESIS OF RHENIUM NANO AND MICRO POWDERS - The process for the synthesis of rhenium powders comprises the injection of ammonium perrhenate powder through a carrier gas in a plasma torch of a plasma reactor operated using a mixture including hydrogen as the plasma gas, yielding metallic rhenium under the following chemical reaction: | 10-01-2009 |
