Copper (II) Oxide
Copper (II) oxide is a black powder compound formed by reacting elemental copper to oxygen. It is also commonly known as cupric oxide.
Copper oxide highly thermally stable. It is insoluble in water but readily dissolved in mineral acids.
Pride-Chem uses advanced manufacturing methods for production of highly pure copper oxide powder. Finer powders are available though additional milling and classification process.
The black powder is commonly used in as colour pigments for glass and ceramics, ferrite cores, animal feeds, wood treatments, metal catalyst, manufacturing of semiconductors in electronic devices and electroplating applications.
Packagings
Pride-Chem can provide copper oxide powder in the following approved UN packaging:
25kg Paper Bags
500kg-1000kg PP Bulk Bags
Other information
Characteristics
Copper (II) oxide is a black free flowing powder but brown high surface area also exist. It is stable in air and moisture at room temperature.
Solubility
It is insoluble in water and alcohols but readily dissolve in mineral acids. It dissolves slowly in ammonium hydroxide solution but quickly in ammonium carbonate or ammonium chloride solutions. Being amphoteric, copper oxide is slightly soluble in strong alkaline solution.
Regulatory Classification
It is a environmentally hazardous substance and is classified as under UN Hazard Class 9.
Preventive Measures
Due to the small particle size, avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed.
