应用
Copper(II) oxide is used as an adsorbent and absorbent, pigment, antifouling agent, wood preservative, optical glass polishing agent, welding flux for bronze materials, agricultural chemical and abrasive. It is used in the preparation of intermediates, oxidizing/reducing agents, surface treating agents and process regulators. It finds use in the manufacture of rayon, phosphors and dry battery cells. It serves as a catalyst in certain chemical reactions of industrial importance. It is also employed in chemical sensors and superconducting materials. Hazardous materials like cyanides, dioxins and halogenated hydrocarbons can be disposed through oxidation with copper oxide.
