Copper oxygen(2-)

Copper oxygen(2-) is an inorganic compound with the chemical formula CuO, commonly known as copper(II) oxide or cupric oxide. This black crystalline solid has a molecular weight of 79.55 g/mol and represents one of the most important copper compounds in industrial applications. It occurs naturally as the mineral tenorite and can be produced synthetically through various oxidation processes of copper or copper-containing materials.

Copper oxygen(2-) appears as a black or dark brown crystalline powder with no distinctive odor. It is practically insoluble in water but soluble in acids and ammonia solutions. The compound has a high melting point of approximately 1,326°C and demonstrates good thermal stability. It exhibits semiconductor properties and can act as a p-type semiconductor, making it valuable in electronic applications.

Copper oxygen(2-) serves multiple industrial purposes including catalyst production for organic synthesis reactions, pigment manufacturing for ceramics and glass coloring, and semiconductor applications in electronics. It is widely used in battery manufacturing, particularly for lithium-ion batteries, wood preservation treatments, and as a precursor for other copper compounds. Additionally, it finds applications in fungicide formulations and metal refining processes.

Safe handling of copper oxygen(2-) requires appropriate personal protective equipment including dust masks, safety goggles, and protective gloves to prevent inhalation and skin contact. Work in well-ventilated areas or use local exhaust ventilation to minimize dust exposure. Avoid generating dust clouds during handling and transfer operations. The compound carries a Warning signal word and requires precautionary measures due to its aquatic toxicity classification.

Copper oxygen(2-) should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials such as strong reducing agents and alkali metals. Keep containers upright and properly labeled according to GHS requirements including the GHS09 environmental pictogram. Store away from water sources and drainage systems due to its aquatic toxicity classification as Aquatic Acute 1 and Aquatic Chronic 1.

In case of skin contact with copper oxygen(2-), immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. In case of ingestion, rinse mouth with water and seek immediate medical attention.

Copper oxygen(2-) disposal must comply with local and national environmental regulations due to its classification as environmentally hazardous (Aquatic Acute 1, Aquatic Chronic 1). Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil. Recovery and recycling of copper content is often preferred over disposal. Consult local authorities for specific waste codes and disposal requirements in your region.

Copper oxygen(2-) is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. It requires appropriate packaging according to UN regulations and proper hazard labeling including the GHS09 environmental pictogram. Transport documents must include the correct shipping name and UN number. Ensure vehicles are properly placarded and drivers have appropriate training for Class 9 materials transport.

Copper oxygen(2-) is subject to CLP regulation requirements for classification and labeling, displaying Warning signal word and GHS09 pictogram due to its aquatic toxicity. It falls under REACH regulation for registration and safety data sheet requirements. The substance is not classified as SVHC (Substance of Very High Concern). Specific environmental regulations may apply due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications.
