Preparation method for flaky cobalt powder in acid medium

Abstract

The invention provides a preparation method for flaky cobalt powder. According to the method, water, cobalt salt, a complexing agent, a cobalt plating brightener, a dispersing agent, an antioxidant, acid, a flaky acidic compound crystal template and a reducing agent serve as raw materials, the surface of the flaky acidic compound crystal template is plated with cobalt by adopting a chemical plating method until cobalt ions react completely, and after the reaction, the flaky cobalt powder is directly obtained through the technological processes of separation, purification and processing treatment without ball milling. The technical scheme of the preparation method has the advantages that the energy consumption is low, the environmental pollution is small, the production process is simple, the process route is short, the large-scale production equipment investment is low, the production efficiency is high, the production cost is low, the dispersing performance and the conductivity of a product are good, the method is suitable for large-scale production, the problems existing in a technology for preparing the flaky cobalt powder through a ball milling method can be solved, and the method has a good industrialization prospect.
