Description

Technical Field

[0001] The utility model relates to the technical field of metal powder particle preparation, in particular to a nano metal powder particle preparation device. Background Art

[0002] Metal powder has good conductivity and can be used to prepare conductive materials in the electronics industry. During its production, chemical reduction is one of the common methods for preparing metal nanoparticles. Its main principle is to use a reducing agent to reduce metal ions into metal nanoparticles. This method has the advantages of low preparation cost and easy control of particle size, so it has been widely used. However, this method also has some defects, such as the inability to control the morphology, distribution, and particle size dispersion of the finished product. In addition, the sol-gel method is another method for preparing metal nanoparticles. Its principle is to use a hydrolysis polymerization reaction to convert metal ions into a gel system, and convert them into metal nanoparticles through calcination and other methods. It also includes arc discharge explosion for the preparation of nano metal powder particles.

[0003] In addition, during the preparation process of the electric explosion method, the electric explosion method uses factors such as high temperature generated by high voltage discharge to melt and vaporize fine metal wires. The metal vapor forms nanometal particles or nanoalloy particles when colliding with inert gas. This method is used in industry to continuously produce nanopowders such as nanometals, alloys and metal oxides. It is currently the most studied and main method for realizing the industrial production of nanometal materials. However, during the preparation process, it is difficult to control the material preparation of metal powders, so improvements are needed. Utility Model Content
