Abstract
A compound powder being comprised of a noble metal and of a nonnoble metal oxide is produced under atomization of salts of these metals in a watery solution and under further utilization of a hot reactor wherein a droplet containing gas flow is moved inside the reactor by operation of a pressure differential produced by a water pump, the powder particles are gravity separated from reaction gases by gas flow reversal at a temperature above the dew point of the gas and the gas is scrubbed following condensation of any water vapor.
