Abstract

The invention discloses an electrolyte for preparing nano-metal powder. The electrolyte comprises the following components of 0.5-7 g / L of a fluorocarbon anionic surfactant or nekal, 3-10 g / L of a nonionic surfactant, 3-15 g / L of an auxiliary agent, 15-50 g / L of metal salt and the balance water; the temperature of the electrolyte is controlled to be 25-50 DEG C, and the nano-metal powder is prepared under the condition of electrodeposition. The electrolyte is good in uniformity, high in stability, small in corrosion amount to polar plates and less in pollution; in the electrodeposition processusing the prepared electrolyte, the nano-metal powder cannot be adhered to an cathode, the self-desorption performance is good, polar plates are easy to clean, and automatic and continuous productioncan be realized; and the prepared nano-metal powder is good in dispersity and easy to collect.

Description

technical field [0001] The invention relates to the technical field of metal powder preparation in metal materials, in particular to an electrolyte for preparing nano metal powder. Background technique [0002] Nanotechnology is a high-tech emerging at the end of the 20th century. It occupies an important position in the field of material science and is expected to become a new economic growth point in the 21st century. The research on the performance, preparation and application of nanomaterials has become a frontier topic of common concern. [0003] As a member of nanomaterials, metal nanopowder has its unique material characteristics. Cobalt, copper, silver, iron, nickel, zinc, etc. are commonly used to prepare metal nanopowder, as well as their alloys and oxides. Metal nanopowders have a special absorption effect on electromagnetic waves. Iron, cobalt, zinc oxide powders and carbon-coated metal powders can be used as high-performance millimeter-wave stealth materials fo...
