preparation example Construction

[0022] One aspect of the embodiments of the present invention provides a method for preparing copper oxide powder, which includes:

[0023] Smelt pure copper to a molten state, and directly atomize the molten copper in an oxygen atmosphere to fully oxidize copper and oxygen to obtain copper oxide powder.

[0024] As one of the preferred solutions, the melting temperature is 1400-1500° C., and the temperature is kept for 20-30 minutes.

[0025] As one of the preferred solutions, when the atomization treatment is performed, the pressure of the oxygen is 1.5-2.5 MPa. Within a certain range, the greater the pressure, the more thoroughly the powder can be pulverized and the finer powder can be obtained. When the oxygen pressure used in the production process is too low, on the one hand, it may lead to incomplete oxidation of copper oxide powder, and it may also cause the suction force in the negative pressure area of ​​the nozzle to be too small, increasing the risk of furnace blo...

Abstract

The invention discloses copper oxide powder and a preparation method thereof. The preparation method of the copper oxide powder comprises the following steps: smelting pure copper into a molten state, directly performing atomization treatment on the copper in the molten state in an oxygen atmosphere, enabling the copper and oxygen to generate sufficient oxidation reaction and obtaining the copper oxide powder. The preparation method of the copper oxide powder, provided by the invention, has the advantages that when the copper oxide powder is prepared by utilizing an atomization method, the pure oxygen is introduced, so that the copper and the oxygen are oxidized at a high temperature in the atomizing process to prepare the copper oxide powder, therefore, the production step is saved, and the production method of the copper oxide powder is widened; the obtained copper oxide powder is relatively concentrated in particle size, uniform in distribution and excellent in performance.

Description

technical field [0001] The invention relates to a preparation method of copper oxide powder, in particular to a copper 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] The metal powder produced by the gas atomization method has excellent performance, uniform particle size distribution, nearly spherical powder shape, fine structure and uniform composition. [0004] Copper oxide has a wide range of uses, in addition to being used as a raw material for making copper salts, it is also widely used in other fields, especially in electronic information products, such as mobile phones, com...
