1. If it is used and stored according to the specifications, it will not decompose. There is no known dangerous reaction and avoid the reducing agent.
2. Hydrogen or carbon monoxide can be reduced to metallic copper at high temperatures. The copper oxide is heated in the air to release oxygen at about 1050 ° C to be reduced to cuprous oxide. If it is in a hydrogen or carbon monoxide gas stream, it can be easily reduced to metallic copper even below 250 °C. Although copper oxide is insoluble in water, it can be dissolved in an aqueous alkali metal hydroxide solution.
Main use of copper oxide
Used as glass, porcelain pigments, desulfurizers, catalysts, also used in the rayon industry as a coloring agent for glass, enamel, ceramic industry, paint anti-cue agent, optical glass polishing agent. Used in the manufacture of dyes, organic catalyst supports and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for oils and fats. Used as a raw material for the manufacture of other copper salts, it is also a raw material for making artificial gemstones.
Copper oxide ecological data and toxicological data and storage methods
Water hazard level 3: It is extremely harmful to water. Even if a small amount of product penetrates into the ground, it will cause harm to drinking water. If there is no government permission, do not discharge the product into the surrounding environment. It is highly toxic and harmful to organic matter in water.
Storage method
1. Store in a dry warehouse.
2. It should be protected from moisture and stored in isolation from strong acid and edible materials. Handle with care when handling, to prevent damage to the packaging.
Toxicological data
1. Acute toxicity: mouse tracheal LDLo: 278mg/kg;
2. Inhalation, ingestion or skin contact may cause a delayed reaction. If skin or eyes come into contact with the substance, rinse immediately with water.
