Reaction Conditions

Reaction Steps

70 ml of purified water was added to 8 g of anhydrous copper acetate (manufactured by Wako Pure Chemical Industries, Ltd.). Thereto was added 2.6 ml of 64 wt % hydrazine hydrate while stirring at 25° C. so as to give a molar ratio of hydrazine to copper acetate of 1.2, thereby to carry out the reaction to obtain a precipitate of cuprous oxide. The average primary particle diameter of the precipitate was 20 nm and the average secondary particle diameter was 800 μm. One gram of the precipitate was added to 9 g of diethylene glycol, followed by subjecting to ultrasonic dispersion to obtain a colloidal dispersion of cuprous oxide. The average secondary particle diameter in the dispersion was 80 nm.
