Through a controlled chemical reduction process, a reduction system is introduced into a high-purity silver salt solution. By precisely controlling PH value, reaction temperature, and surfactant concentration, the directional growth of silver micro-nano particles is achieved. The resulting silver powder features adjustable particle size, super dispersibility, and excellent electrical conductivity.
Micro and nano copper powders prepared by liquid phase chemical reduction method are high-purity powders obtained by reducing copper salts as precursors, generating copper metal particles by reducing agent in liquid phase system, after washing, drying and surface treatment.
Nano nickel powders prepared by liquid phase chemical reduction method are high-purity nano-powders obtained by using nickel salts (e.g. nickel sulfate, nickel nitrate) as precursors, reducing nickel metal particles through strong reducing agents (e.g. hydrazine hydrate, sodium borohydride) in a liquid phase system, and then undergoing surface modification, washing, and drying. The nickel powders exhibit properties such as high magnetism, corrosion resistance, catalytic activity, etc., making it widely applicable in energy, electronics, catalysis, and functional materials.
