preparation example Construction

[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:

Abstract

The invention discloses cuprous oxide powder and a preparation method thereof. The preparation method of the cuprous oxide powder is as follows: smelting pure copper to a molten state, directly atomizing the copper in the molten state in a nitrogen and oxygen mixed atmosphere for oxidation reaction of the copper and oxygen to obtain the cuprous oxide powder. During production of the cuprous oxide powder by the atomization method, the nitrogen and oxygen mixed atmosphere is introduced for high-temperature oxidation of the pure copper and the oxygen in the atomization process to prepare the cuprous oxide powder, meanwhile because of lack of oxygen, cuprous oxide cannot continue to react with the oxygen to form copper oxide. The preparation steps of the method are efficient, fast and convenient, production steps are saved, the production method of the cuprous oxide powder is broadened; and the cuprous oxide powder prepared by the preparation method has relatively concentrated and uniform particle size distribution and excellent physical properties, and is easy to use later.

Description

technical field [0001] The invention relates to a preparation method of cuprous oxide powder, in particular to a cuprous oxide powder and a preparation method thereof, belonging to the technical field of metal powder. Background technique [0002] The gas atomization method is a method of directly crushing liquid metal or alloy to obtain powder. It is widely used and its production scale is second only to the reduction method. It can produce metal powders such as lead, tin, aluminum, zinc, copper, iron, nickel, etc. , can also produce pre-alloyed powder. [0003] Cuprous oxide is an important inorganic chemical raw material, which is widely used in the fields of coatings, glass, ceramics, plastics, agriculture and industrial catalysis. In my country, the amount of cuprous oxide is increasing year by year, and the research on cuprous oxide is relatively active in recent years. At present, there are many methods for preparing cuprous oxide, but it is rare to obtain cuprous o...
