Abstract
A cuprous oxide powder is produced by the steps of discharging a molten copper, which is kept at a temperature at or higher than the melting point and at or lower than 1450.degree. C. and contained in a container having a nozzle at a bottom, from the nozzle into a reactor vessel disposed below the container to form a downward flow of the molten copper, atomizing the downward flow by a jet stream of an oxygen-contained gas and, thereby simultaneously, oxidizing the molten copper to form cuprous oxide, cooling liquid droplets or solid particles of the thus formed cuprous oxide and then collecting the droplets or particles from the reactor vessel. A cuprous oxide powder can be produced, without requiring a large-scale production facility, in simple steps, and efficiently and continuously.
