When copper, cuprous oxide and cupric oxide particles were heated in a thermogravimetric analyzer under nitrogen containing trace amounts of oxygen, the particles increased 25, 13 and 0% in weight, respectively, due to complete oxidation to cupric oxide.
2]O)-based organic conversion coating has provided improved physical strength and much greater acid resistance compared to the 100% cupric oxide (CuO) coatings (comprised of dendritic crystals), generated by the older black oxide processes.
Research: Participants in the Age-Related Eye Disease Study (AREDS) were randomly assigned to receive daily antioxidants (vitamin C, 500 mg; vitamin E, 400 IU; beta-carotene, 15 mg), zinc and copper (zinc, 80 mg; cupric oxide, 2 mg), antioxidants plus zinc and copper, or placebo.
