摘要： A fine powder of metallic copper, suitable as a material for electroconductive pastes, and having a BET diameter of 3 μm or less, large crystallite size, high dispersibility and particles of high sphericity and a process for producing the same. More specifically, a fine powder of metallic copper having a BET diameter of 3 μm or less, particles of high sphericity and crystallites of 0.1 to 10 μm in size, and more preferably containing oxygen at 0.3% by weight or less. Moreover, the fine powder of metallic copper can be produced stably and efficiently by blowing an ammonia-containing gas onto molten copper kept at 1120° C. More specifically, it can be produced more stably and efficiently by blowing ammonia at 0.015 L/minute or more per unit area (cm2) of the molten copper.

摘要： A method for producing copper fine particles by heating and reducing an oxide, hydroxide, or salt of copper included in a solution of ethylene glycol, diethylene glycol, or triethylene glycol, the method comprising controlling a total halogen content of the solution to be less than 20 ppm by mass relative to copper and adding a water-soluble polymer as a dispersant such as polyethyleneimine and a noble metal compound or noble metal colloid for nucleation to the solution. This method makes it possible to provide copper fine particles for use in a wiring material, which are very fine as small as 50 nm or less in average particle size and high dispersibility, extremely low undesirable halogen content, and can be sintered at a low temperature.
