| 摘要 |
A process for manufacturing metal containing powder, the process including the steps of: (a) mixing at least one metal oxide powder with Ca or Mg granules and/or calcium hydride in granule or powder form to form a mixture; (b) maintaining said mixture under an H2 atmosphere, at a temperature between 1000° C. and 1500° C. for 1-10 hours, followed by: (c) recovering metal containing powder. Metal hydride powder may be recovered. The process may further include between steps (b) and (c): (d) switching the H2 atmosphere to an Ar atmosphere and maintaining the mixture thereunder for a period of 20 minutes to 5 hours, followed by: (e) cooling under Ar atmosphere, wherein metal powder is recovered in step (c). |
