[0086] The difference between the second embodiment and the first embodiment is that: after the metal particles are formed, the metal particles are cleaned to further improve the purity of the metal particles.

[0087] In this embodiment, the metal particles are cleaned to remove impurities on the surface of the metal particles to further improve the purity of the metal particles; at the same time, since there are fewer impurities on the surface of the metal particles, it is not necessary to use more cycles of repeated cleaning, and the efficiency Higher; and because the formation of metal particles by mechanical processing is avoided, a small amount of impurities will not be embedded in metal particles, thus reducing the difficulty of cleaning.

[0088] Specifically, a cleaning solution is used to clean the metal particles.

[0089] If the metal particles are exposed to oil pollutants, such as oil film materials, it is necessary to remove the oil pollutants on the surface of ...

Abstract

The invention provides a metal particle forming method and a metal particle preparing device. The metal particle forming method comprises the steps that a metal raw material and a heat preservation container are provided, and the bottom of the heat preservation container is provided with holes; the metal raw material is melted, and metal molten liquid is formed; the metal molten liquid is poured into the heat preservation container and dripped out of the holes, and independent metal liquid drops are formed; and the metal liquid drops are solidified, and metal particles are formed. According to the metal particle forming method, the purity of the metal particles can be guaranteed, and the technology efficiency is improved.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a method for forming metal particles and a device for preparing metal particles. Background technique [0002] In the field of metal processing, it is necessary to process the entire metal block into metal particles for use in different fields. [0003] For example, the aluminum block is processed into aluminum particles, which are used in the process of preparing alumina by the direct hydrolysis method of activation of high-purity aluminum. In the process of high-purity aluminum activation and direct hydrolysis to prepare alumina, aluminum particles are used as one of the raw materials for the reaction, which can increase the reaction contact area and improve the reaction efficiency. When the alumina is used to prepare sapphire with a purity of 99.999% or more, the purity of the alumina needs to be relatively high, and at this time, the purity of the aluminum particles is also r...
