Product Description
Copper oxide is an inorganic substance, the chemical formula CuO, is a black oxide of copper, slightly amphoteric, slightly hygroscopic. [1] Insoluble in water and ethanol, easily soluble in acid, stable to heat, decomposition of oxygen at high temperatures. Copper oxide is mainly used in the production of rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass and so on.

Main usage
broadcast
1, can be used as an organic synthesis catalyst, used as an analytical reagent (for nitrogen), oxidant, catalyst and petroleum desulfurizer, can also be used for the determination of carbon in organic compounds.
2, used as colorant for glass, enamel, ceramic industry, anti-wrinkle agent for paint, polishing agent for optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for oils and fats. It is used as a raw material for the manufacture of other copper salts, and is also a raw material for the manufacture of artificial gems.
3, nano copper oxide use
(1) It is widely used as an important inorganic material in catalysis, superconductivity, ceramics and other fields.
(2) Used as catalyst and catalyst carrier and electrode active material.
(3) Used as colorant for glass and porcelain, optical glass polishing agent, catalyst for organic synthesis, oil desulfurizer, hydrogenating agent.
(4) Manufacture of artificial gemstones and other copper oxides.
(5) For the manufacture of rayon, as well as gas analysis and determination of organic compounds.
(6) It can also be used as a burning rate catalyst for rocket propellant. Nano copper oxide powder has better catalytic activity and selectivity than large size copper oxide powder and others.
