Copper oxide (CuO) is a black oxide of copper, slightly amphoteric and slightly hygroscopic. The relative molecular mass is 79.545, the density is 6.3~6.9 g/cm, and the melting point is 1326°C. Insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solutions, slowly soluble in ammonia solution, and can react with strong alkali.
Copper oxide is mainly used to make rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc.
It is used to make rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and is also used for hydrogen production, catalysts, green glass, etc. Laboratory preparation; the chemical equation can be obtained by heating copper powder in the air; 2Cu+O₂====2CuO; used as raw material for nickel-zinc ferrite and thermal components in the production of magnetic materials; used as an organic reaction catalyst to manufacture artificial Wire and other copper compounds; manufacturing pyrotechnics, catalysts, and electroplating industries.
Exothermic welding (fire mud welding, hot melt welding)
The main purpose of copper oxide sheet is exothermic welding.
Exothermic welding (fire clay welding, hot melt welding) is to produce liquid high temperature copper liquid and alumina residue through the chemical reaction (exothermic reaction) of aluminum and copper oxide, and use the high temperature generated by the exothermic reaction to achieve high performance Modern welding process for electric welding.
3CuO+2Al======(heating) 3Cu+Al2O3
This reaction is carried out in a high-temperature graphite mold, and the exothermic reaction process takes only a few seconds to complete.
