What is Copper oxide powder?
Copper oxide is an inorganic substance with the chemical formula CuO, which is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water and ethanol, soluble in acid, stable to heat, and decomposes oxygen at high temperatures. Copper oxide is mainly used to make rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizes, pesticides, hydrogen production, catalysts, green glass and so on.
Applications of Copper oxide powder
As an important p-type semiconductor material with a narrow band gap (1.2-1.5 ev), copper oxide has been widely used in catalysts, sensing materials, superconducting materials, thermoelectric materials, glass, ceramics, lithium-ion batteries and even medicine because of its unique properties, such as good thermal stability and photochemical stability, high-temperature superconductivity, high electrochemical activity, non-toxicity and low-cost preparation method.
1. Copper oxide is mainly used as a green, red or blue pigment for glass, ceramics and enamel, polishing agent for optical glass, desulfurizing agent for oil; a catalyst for organic synthesis; and manufacturing artificial gem and other copper oxides.
2. The industrial uses of copper oxide mainly include rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizes, pesticides, hydrogen production, catalysts and green glass.
3. Chemical applications: as oxidant, determination of carbon in gas analysis, as organic reaction catalyst, making rayon and other copper compounds.
Manufacturing method of Copper oxide powder
1. Thermal decomposition of copper carbonate
Dissolve copper powder or copper wire completely with as little as 6mol/L nitric acid in a fume hood. If the solution is opaque, it needs to be filtered. In addition, sodium carbonate solution is mixed with copper nitrate solution and boiled to generate a black basic salt precipitate. When the solid is settled, the supernatant is removed, fully washed, filtered and dried by decantation. Please put it on an evaporating dish, heat it with a low fire under full stirring, and decompose it into copper oxide.
2. Nitrification of copper wire or copper powder
Dissolve copper wire or copper powder in 6mol/L nitric acid to keep a little excessive copper, heat it to pH 3-4 to remove iron hydroxide precipitation, then mix it with 10% (mass) sodium carbonate solution, heat it to boil, and precipitate basic salt, discard the supernatant, fully wash it with water, filter and dry it. The dried basic copper carbonate is heated and decomposed into black copper oxide powder under low fire with sufficient stirring. When carbon dioxide is no longer produced, the decomposition is complete.
Harm of copper oxide
The harm of copper oxide to the human body causes metal smoke fever in patients, which is characterized by chills, elevated body temperature and respiratory irritation. Long-term exposure can cause irritation of the respiratory tract and conjunctiva, epistaxis, bleeding point or ulcer of the nasal mucosa, and even perforation of the nasal septum or dermatitis. Copper oxide is a black oxide of copper, which is slightly hygroscopic. The relative molecular weight is 79.545, the density is 6.3 to 6.9g/cm, and it is insoluble in water and ethanol.
