Preparation method of flaky cobalt powder in alkaline medium

Abstract

The invention provides a preparation method of flaky cobalt powder in an alkaline medium. The preparation method of the flaky cobalt powder in the alkaline medium comprises the steps that water, cobalt salt, a complexing agent, a cobalt plating brightener, a dispersing agent, an antioxidant, alkali, flaky alkaline compound crystal templates and a reducing agent are used as raw materials, a chemical plating method is adopted, the surfaces of the flaky alkaline compound crystal templates are plated with cobalt until cobalt ions completely react, after reaction is ended, the technological processes of separation, purification and processing treatment are conducted, and the flaky cobalt powder is directly obtained without ball milling. The preparation method of the flaky cobalt powder in the alkaline medium has a series of advantages of being low in energy consumption, low in environmental pollution, simple in production technology, short in operational path, small in large-scale production equipment investment, high in production efficiency and low in production cost, achieving that the dispersing performance and the catalytic performance of the product are good and the like. The preparation method of the flaky cobalt powder in the alkaline medium is suitable for large-scale production, solves the problems existing in the technology of preparing the flaky cobalt powder with a ball-milling method and has good industrial prospects.

Description

technical field [0001] The invention relates to a preparation method of flaky cobalt powder in an alkaline medium, and belongs to the technical field of preparation of metal powder materials. Background technique [0002] Metal powders are divided into four types according to particle shape: spherical, random particle, flake and wire. Different from spherical metal powder and granular metal powder, flake metal powder has excellent catalytic performance, excellent sintering performance, excellent thixotropic performance, excellent adhesion, good shielding effect, excellent electromagnetic wave reflection ability and excellent Excellent electrical conductivity makes it widely used in chemical catalysis, powder metallurgy, conductive coatings, conductive adhesives, conductive inks and conductive pastes. [0003] At present, spherical metal powders or granular metal powders are mostly used in the fields of chemical catalysis, electromagnetic shielding coatings, radar wave refle...
