Cuprous oxide can be described as a bright red powder. It is nearly insoluble in water and can be disproportionately transformed into divalent copper or copper in acidic solution. Then, it slowly oxidizes into black copper dioxide in moist atmosphere. Purity: 99% Particle size: 50nm, micron Cuprous Oxide Cu2O powder Curous oxide or cu2o are oxides of monovalent copper. Which chemical name should be used for Cu2O? All Cu2O chemical names are correct: Copper (1+), oxidecopper, or copper oxide Cu2O (a bright red powdery liquid) is almost insoluble when dissolved in water. This metal reacts poorly to copper elements and divalent copper in acidic solution. In humid environments, it slowly turns black. Copper oxide. Cuprous oxide is used primarily in antifouling paints on ships’ bottoms (used to kill marine low-level animals), as well as insecticides and various copper salts. It also helps with the preparation of copper alloy plating and copper plating solutions. The cuprous oxide is safe to use if it’s stored according to its instructions. Copper salts are not produced by cuprous oxide in dilute sulfuric and dilute nitric. It will rapidly turn blue when exposed to the atmosphere. While cuprous oxide remains stable in dry conditions, the metal will oxidize slowly in humid environments to create copper oxide. This makes it an excellent oxygen scavenger. Cuprous oxide cannot be dissolved in water. It dissolves in the presence of concentrated hydrohalic acid and aqueous solution. It can be easily dissolved in an alkaline solution. For sale TRUNNANO is an trusted supplier of Cuprous Oxide. You can send us an inquiry regarding the current Cuprous Oxide prices anytime. How does CuO differ from Cu2O? Cu2O cuprous or CuO . Cu2O is obtained using a solution containing copper oxide or an oxidation (II), solution of the sulfur dioxide solution. Copper can be found in many wood preservers. You can use it to create different glazes. Is cuprous oxide dangerous? Consumption of toxic substances if swallowed. Ingestion of skin may cause harm if it is not removed from the skin. May cause skin irritation. Eyes may cause irritation. Cuprous oxide Cu2O powder Performance: Cuprous oxide (also known copper I Oxide) is an inorganic compound that has the formula Cu2O. It is one the major copper oxides. This solid brown-red powder can be used in antifouling sprays. Cuprous microparticles is a solid, stable red powder made by the reduction Cu2+ solution. They contain Cu+ ions with linear coordination to oxygen. Technical Parameters of Cuprous Oxide Cu2O powder






















How does Cuprous Oxide cu2O powder get made? Here are some of the most common methods to make cuprous oxide. 1. Dry method. The copper powder can be mixed with copper dioxide after eliminating impurities and put into a calcining furnace. It will then be heated to 800-900°C, which is used to make cuprous oxide. Use a magnet for mechanical impurities to be absorbed. Then, pulverize the mixture to 325 mesh in order to make cuprous oxide. When copper sulfate has been used as the source material, it is necessary to first reduce the copper with iron. All subsequent reactions are exactly the same as for copper powder. 2. Method of glucose reduction: Copper sulfate solution is added to glucose, and then the solution is combined with sodium hydroxide to create the cuprousoxide. The cuprous oxide is extracted by filtering, drying, and crushing the product. 3. An electrolysis procedure in iron. The anode is the copper cast plate. The cathode is the red copper plates. KOHOL chromate is the additive. Salt solution is the electrolyte. Electrolysis can be performed at a temperature of 70 °C, potassium chloride 0.3 0.5 g/L and current density 1500 A/m2. The cuprous oxide will then be produced by electrolysis. 4. Method to reduce hydrazine levels: Mix 35mL 20% Hydrazine in 50mL of high-concentration Copper acetate aqueous water. This will lower the copper divalent ions. It turns green immediately and produces nitrogen gas. The solution will turn yellow to an orange-yellow color and eventually precipitate. It was then washed with water and ethanol. Excessive hydrazine may cause cuprous oxide to become metallic copper. Therefore, it is important that the amount of hydrazine used should be kept in check. There are many ways to make Copper(I). The most common method is to oxidize copper metal. This results in 4 Cu+ O2 + 2 Cu2O. The rate at which this happens and the subsequent oxidation to copper(II oxides) are affected by acids and water. 5. Film solution glucose reduction synthesis: The 50g and 75g of copper sulfate pentahydrates are respectively dispersed in 200mL each cold water. After cooling to room temperature, the solutions are combined. For an alkaline mixture, 75g of sodium hydroxide were also dissolved into 200 mL. As you stir the mix, add the alkali solutions slowly to it. Keep the temperature at a constant level so the solution doesn’t turn too dark. To precipitate red cuprous dioxide, heat the divalent copper sodium solution to boiling. Then, mix 10% glucose with water until the solution turns blue. It should be boiled in 1 L of cold water. After it has cooled, you can add more water. 6. For direct oxidation, you can use platinum wire to attach metallic copper to a tubular electric furnace. After heating it to 1000°C for 24 hour in a nitrogen atmosphere with 1% oxygen (volume fraction), cuprous oxide will be formed. You can also heat the mixture of metallic copper with copper oxide in a vacuum tube for 5 hours. Then, you will get cuprous oxide. Cuprous Oxide uses / Cu2O uses: Cupric oxide is used to create blue, red and green glazes in ceramics. Also, it is not recommended to be used in animal feeds as an dietary supplement. Because of its low bioactivity it is very difficult to absorb copper. Cuprous oxide is used for welding with copper alloys. Cuprous oxide can be used to make marine coatings. It’s a common pigment, fungicide, and antifouling ingredient. Do you know what cuprous oxide is used for? 1. It is suitable for use in pesticides. 2. This product is safe for use with antibacterial fabrics and clothing. 3. Cuprous oxide also works well as an agricultural pesticide. 4. This antiseptic is ideal for ship primers that prevent microorganisms and pollution. 5. It is used to make various copper salts, analytical reagents, and other chemicals. 6. As a catalyst in organic synthesis. Cuprous oxide Cu2O powder storage condition: Cuprous Oxide Cu2O Powder should be kept in a dry, cool environment. It should not be exposed to air. Packing & Shipping cuprous oxide Cu2O powder You can pack it in two plastic bags with the inside. Packing of cuprous oxide Cu2O powder: vacuum packaging, 100g to 500g, 1 kg/bag, 25kg/barrel and as per your request. shipping: can be shipped by sea, air or express, once the payment has been received.
