Abstract

The invention discloses equipment for preparing metal nano powder through an electric arc method. The equipment comprises a vacuum chamber, wherein a crucible and a liquid nitrogen tank are arranged in the vacuum chamber, and the liquid nitrogen tank is located above the crucible; an arc charger penetrating through the top of the vacuum chamber is arranged on the vacuum chamber, and an electrode stem of the arc charger extends in the direction of the crucible and can be in contact with metal placed in the crucible; and a collecting box and a plurality of external pipes penetrating through the vacuum chamber are arranged on the liquid nitrogen tank, so that nano powder with superfine and high-purity characteristics can be prepared.

Description

technical field [0001] The invention relates to the technical field of nano-powder preparation, in particular to equipment for preparing metal nano-powder by an arc method. Background technique [0002] Nanopowder material refers to particle aggregates with a particle size of less than 100nm. It is a new type of high-tech material. Due to the small size of the particles, it has properties that other materials cannot achieve. It has broad applications in the fields of powder metallurgy, fine chemicals, and electronic information. Prospects. [0003] Arc metal nanopowder preparation equipment is to heat the metal in a low-pressure inert gas to vaporize it, and then crystallize to form nanoparticles. The metal powder particles produced by the existing metal nanopowder equipment are relatively large, which is difficult to meet the modern society's demand for nanometer powder. The requirements for powder are getting higher and higher. Contents of the invention [0004] In ord...
