Abstract

The invention provides a preparation method of a piece shaped cobalt powder. The method is characterized in that water, cobalt salt, a complexing agent, a cobalt plating brightener, a dispersing agent, an antioxidant, a sublimable piece shaped compound crystal die plate and a reducing agent are used as the raw materials; cobalt is plated on the surface of the sublimable piece shaped compound crystal die plate by a chemical plating method until cobalt ions completely react; after the reaction, the product is separated, purified and processed, and thus the piece shaped cobalt powder can be directly obtained without ball milling. According to the technical scheme, the preparation method has a series of advantages such as low energy consumption, low environmental pollution, simple production process, simple and short technical routes, small investment on scale production equipment, high production efficiency, low production cost, high product dispersing performance and high product conductivity; the method is suitable for scale production; the problems in a technology for preparing the piece shaped cobalt powder by a ball milling mode can be solved; and the method has a good industrialization prospect.

Description

technical field [0001] The invention relates to a preparation method of flaky cobalt powder, which 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 reflecting coatings, cond...
