Production of noble metal/non-noble metal oxide powder

In a method for the production of powder being comprised of a noble metal and of a nonnoble metal oxide under atomization of salts of these metals in watery solution under further utilization of a hot reactor and a hot gas filter with sedimentation chamber, and a collection chamber underneath the improvement comprising:

• atomizing the metal solution in the hot reactor;
• moving a droplet containing gas flow inside the reactor by operation of a pressure differential produced by a water pump;
• the gas resulting at least in parts from reaction in the closed chamber reactor;
• running the powder and the gas through the sedimentation chamber of the hot gas filter under support of gravity and separating the powder particles from reaction gases at a temperature above the dew point of the gas by deflecting the reaction gases and laterally into the hot gas filter while the powder is collected below in the collection chamber;
• and
• scrubbing the gas extracted from the filter, in a scrubber following condensation of any water vapor.
