[0022] One aspect of the embodiments of the present invention provides a method for preparing cuprous oxide powder, which includes:
[0023] The pure copper is smelted to the molten state, and the molten copper is directly atomized in a mixed atmosphere of oxygen and nitrogen, so that the copper and oxygen undergo an oxidation reaction to obtain cuprous oxide powder.
[0024] As one of the preferred solutions, the volume ratio of oxygen and nitrogen in the mixed atmosphere of oxygen and nitrogen is 45:55˜50:50, especially preferably 50:50. If the proportion of nitrogen in the mixed gas is too low during the production process, a part of the cuprous oxide powder will continue to react with excess oxygen to form copper oxide powder, resulting in the impurity of the obtained cuprous oxide powder. If the proportion of nitrogen in the mixed gas is too high during the production process, some copper water cannot react with oxygen, and there will be a part of copper powder in the gen...
Embodiment 1
[0043] The method for preparing cuprous oxide powder of the present embodiment comprises the following steps:
[0044] A. Put the pure copper raw material into the gas atomization powder making equipment, first heat the pure copper to keep it warm, and then melt it to a molten state at 1100 ° C. The atomization powder making equipment can be obtained through commercial channels, etc., and will not be done here Too much detail.
[0045] B. Atomize the pure copper material in the molten state, introduce a mixed gas of oxygen and nitrogen, the volume ratio of oxygen and nitrogen is 45:55, and the gas pressure is 1MPa, and the cuprous oxide powder is obtained. The scanning electron microscope picture can be found in figure 2 , and its particle size is 35-45 microns.
