Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun. The success of nuclear fusion technology will lead to the development of copper oxide.

  About Cuprous Oxide CuO powder:   Copper oxidation states: Copper exists in two oxidation states: +1 and +2.  Copper(Ⅱ) oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphiphilic, slightly hygroscopic. Copper oxide is weak base. Black copper oxide is CuO, and red copper oxide is Cu2O. Copper oxide is virtually insoluble in water or alcohols; copper oxide dissolves slowly in ammonia solution but quickly in ammonium carbonate solution; it is dissolved by alkali metal cyanides and by strong acid solutions; hot formic acid and boiling acetic acid solutions readily dissolve the oxide. Copper oxide is mainly used to make rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, pesticides, and also for hydrogen production, catalysts, and green glass. Cu oxide CuO is produced on a large scale by pyrometallurgy, which is a stage of extracting copper from ore. The ore is treated with an aqueous mixture of ammonium carbonate, ammonia and oxygen to obtain copper (I) and copper (II) amino complexes, which are extracted from the solid. These complexes are decomposed with steam to produce CuO. Cupric oxide is used as a precursor in many copper-containing products such as wood preservatives and ceramics. The mean daily dietary intake of copper in adults ranges between 0.9 and 2.2 mg. Common routes of cupric oxide exposure include ingestion, dermal exposure and inhalation. Copper(II) oxide nanoparticles ( NPCuO) have industrial applications as antimicrobial agents in textiles and paints and catalysts in organic synthesis. They may also be produced from electronic wastes. Cupric oxide poses potential health and environmental concerns due to toxic and muta particles generating reactive oxygen species. Copper oxide for sale: Feel free to send an inquiry to get the latest copper oxide price if you would like to buy copper oxide p o wder in bulk. Performance of Copper Oxide CuO Powder: Copper oxide is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solutions. It slowly dissolves in ammonia solution and can react with strong bases. Copper oxide is mainly used for making rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, insecticides, hydrogen production, catalysts, green glass, etc. Technical Parameter of Copper Oxide CuO Powder:

  How is Copper Oxide CuO powder produced?   There are several methods of industrial production of copper oxide 1. Copper powder oxidation method Using copper ash and copper slag as raw materials, it is roasted and heated with coal gas for preliminary oxidation to remove moisture and organic impurities in the raw materials. The generated primary oxide is naturally cooled, and after pulverization, it undergoes secondary oxidation to obtain crude copper oxide. The crude copper oxide is added to a reactor pre-installed with 1:1 sulfuric acid, and the liquid is reacted with heating and stirring until the relative density of the liquid is doubled, and the pH value is 2 to 3 as the end of the reaction, and a copper sulfate solution is generated. After clarification, under heating and stirring conditions, iron shavings are added to replace copper and then washed with hot water until there is no sulfate and iron. After centrifugal separation, drying, oxidation roasting at 450°C for 8 hours, cooling, crushing to 100 meshes, and then oxidation in an oxidation furnace to obtain copper oxide powder. 2. Nitration of copper wire or copper powder Dissolve the copper wire or copper powder in 6mol/L nitric acid to keep the copper in excess, heat the solution to a pH value of 3-4 to remove the iron hydroxide precipitate, then mix it with 10% (mass) sodium carbonate solution and heat to boiling. Alkaline salt is precipitated, discard the supernatant, wash thoroughly with water, filter and dry. The dried basic copper carbonate is heated and decomposed into black copper oxide powder under a small fire with sufficient stirring: CuCO3·Cu(OH)2=2CuO+CO2↑+H2O When no more carbon dioxide is produced, the decomposition is complete. 3. Copper nitrate thermal decomposition method The electrolytic copper is dissolved in dilute nitric acid and evaporated to dryness on a water bath, and then heated in a desiccator from 90°C to 120°C very slowly. When the soft basic salt is formed, it is boiled in water, filtered and dried; then it is slowly heated to 400℃ to remove most of the nitric acid; then crushed and heated to 850℃ for 1h to decompose into oxidation copper. To make the reaction more complete, the product can be pulverized again, heated at about 700°C for 1 hour, and then placed in a desiccator to cool. 4. Conductive water dissolution method Dissolve high-purity copper nitrate with conductive water, filter, add excess high-purity NH3·H2O to the clear liquid, filter out impurities and precipitate, and use high-purity nitric acid to neutralize the filtrate to precipitate copper hydroxide. Filter, wash once with conductive water, add nitric acid to dissolve the precipitate, add high-purity ammonium carbonate to precipitate copper carbonate, then wash, spin dry, dry in an oven at 200°C, burn at 450-550°C for 3 to 4 hours, and get Spectral pure copper oxide: 5. Copper carbonate thermal decomposition method Put copper powder or copper wire in a fume hood with as little 6mol/L nitric acid as possible to completely dissolve it. If the solution is opaque, it needs to be filtered. Besides, the sodium carbonate solution is mixed with the copper nitrate solution and boiled to generate black basic salt precipitation. When the solid settles, discard the supernatant liquid, fully wash, filter, and dry by decantation. Put it on an evaporating dish and heat it with a small fire with sufficient stirring to decompose it into copper oxide. Copper Oxide Uses : As a significant product of copper mining, copper(II) oxide is the starting point for the production of other copper salts. For example, many wood preservatives are produced from copper oxide. Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes. It is also incorrectly used as a dietary supplement in animal feed. Due to low bioactivity, negligible copper is absorbed. It is also used when welding with copper alloys. A copper oxide electrode formed part of the early battery type known as the Edison–Lalande cell. The copper oxide was also used in a lithium battery type. Besides, copper(II) oxide can be used as catalysis, superconductivity, ceramics; and catalyst carriers, electrode activity materials; glass, porcelain colorants, optical glass polishing agent, oil of desulfurized; the propellant rocket fuel speed catalyst. Storage Condition of Copper Oxide CuO Powder： Copper Oxide CuO Powder should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordina.
