Cuprous oxide particles, cuprous oxide particle slurry, and method for producing cuprous oxide particles

摘要

Problem to be solved: to provide a method of producing a copper oxide particle, a copper oxide particle slurry, and a copper oxide fine particle capable of effectively improving the dispersibility of a copper oxide particle in a slurry.The copper oxide particles of the present invention have a zeta potential of - 10 MV or less when dispersed in pure water.The method for producing a copper oxide particle is to contain at least one of the selections of the antidepressant agent from the group consisting of a polysaccharide, a mica and a collagen peptide in a copper sulfate aqueous solution containing a reducing sugar, a denaturation inhibitor and an alkali, and the pH is kept at 8 to How to.No selection
