COLLOIDAL DISPERSION OF CUPROUS OXIDE

摘要

PROBLEM TO BE SOLVED: To prepare a stable colloidal dispersion containing cuprous oxide in a high concentration, and stable to the change with the passage of time. SOLUTION: This colloidal dispersion of the cuprous oxide contains ≥10 wt.% fine particles of the cuprous oxide. The average diameter of the secondary particles of the cuprous oxide is ≤80 nm, and the viscosity measured at 25°C at a shearing stress within a region of 1×10-1s-1-1×102s-1by using a cone-plate type rotary viscometer is ≤100 mPa s.
