About Cuprous Oxide Cu2O powder:
Cuprous oxide is an oxide of monovalent copper. What is the correct chemical name for Cu2O? Cuprous oxide, Copper(1+) oxide copper or Dicopper oxide all is the correct chemical name for Cu2O. Cu2O is a bright red powdery solid, almost insoluble in water. It disproportionates to divalent copper and copper element in acidic solution, and gradually oxidizes to black in the humid air. Copper oxide. Cuprous oxide is mainly used in the manufacture of antifouling paint on the bottom of ships (used to kill low-level marine animals), insecticides, various copper salts, analytical reagents, red glass, and the preparation of copper plating and copper alloy plating solutions. Our company product cuprous oxide for sale.

If used and stored in accordance with the specifications, the cuprous oxide will not decompose, there is no known dangerous reaction, avoid oxides, moisture/humidity, air. Red cuprous oxide does not generate copper salts in dilute sulfuric acid and dilutes nitric acid. Will quickly turn blue in the air. TRUNNANO is a trusted global Cuprous Oxide supplier. Feel free to send an inquiry about the latest price of Cuprous Oxide at any time. Although cuprous oxide is stable in dry air, it will slowly oxidize in humid air to produce the copper oxide, so it can be used as an oxygen scavenger; in addition, it can be easily reduced to metallic copper with a reducing agent. Cuprous oxide is insoluble in water, and it dissolves by forming a complex with aqueous ammonia solution and concentrated hydrohalic acid. It is easily soluble in an alkaline aqueous solution. What is the difference between CuO and Cu2O? Cu2O was obtained by a solution of copper oxide metal or an oxidation solution (II) solution of the sulfur oxide solution, and CuO was obtained by extracting copper metal metallurgical methods from the ore. Many wood preservatives are made of copper. It is also used as pigments to produce different glaze.
Is cuprous oxide dangerous? Ingestion Toxic if swallowed. Skin May be harmful if absorbed through the skin. May cause skin irritation. Eyes May cause eye irritation.
Performance of Cuprous Oxide Cu2O powder:
Cuprous oxide Cu2O, also named Copper I Oxide, is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper. This brown-red solid powder is a component of some antifouling paints. Cuprous nanoparticles are a stable, red solid powder formed by the reduction of Cu2+ solutions and contain Cu+ ions in linear coordination to oxygen.

How is Cuprous Oxide Cu2O powder produced?
The main methods for preparing cuprous oxide are as follows:
1. Dry method: The copper powder is mixed with copper oxide after removing impurities, and then sent into the calcining furnace to be heated to 800-900°C to be calcined into cuprous oxide. After taking it out, use a magnet to absorb mechanical impurities, and then pulverize to 325 mesh to prepare cuprous oxide. If copper sulfate is used as the raw material, the copper in the copper sulfate is first reduced with iron, and the subsequent reaction steps are the same as the method using copper powder as the raw material.
2. Glucose reduction method: the copper sulfate solution is mixed with glucose and then added with sodium hydroxide solution to react to produce the cuprous oxide, which is filtered, rinsed, dried and crushed to obtain the cuprous oxide product.
3. Electrolysis method in iron: in the electrolytic cell lined with polyvinyl chloride, the cast copper plate is used as the anode, the red copper plate is used as the cathode, potassium chromate is used as the additive, and the salt solution is used as the electrolyte. Under the conditions of 290～310g/L, potassium chromate 0.3～0.5g/L, temperature 70～90 ℃, pH 8～12, current density 1500 A/m2, electrolysis will produce the cuprous oxide, which will be separated by precipitation, rinsed, Filter and dry to obtain cuprous oxide.
4. Hydrazine reduction method: Pour 3～5mL 20% hydrazine aqueous solution into 50mL high-concentration copper acetate aqueous solution to reduce the divalent copper ions. The solution turns green at first and generates nitrogen gas. After a period of time, yellow to orange-yellow cuprous oxide is precipitated. The precipitate was washed with water, ethanol and ether. Because excessive hydrazine can further reduce the cuprous oxide to metallic copper, the amount of hydrazine should not be excessive. How do you make Cu2O? Copper(I) oxide may be produced by several methods. Most straightforwardly, it arises via the oxidation of copper metal:
4 Cu + O2 → 2 Cu2O. Additives such as water and acids affect the rate of this process as well as the further oxidation to copper(II) oxides.
5. Glucose reduction synthesis method of film solution: 50g copper sulfate pentahydrate and 75g potassium sodium tartrate are respectively dissolved in 200mL cold water, and the two are mixed when the solution is cooled to room temperature. In addition, 75 g of sodium hydroxide was dissolved in 200 mL of water to prepare an alkaline solution. While stirring the mixed solution, slowly add the alkali solution, and be careful to maintain the temperature of the solution, so that the temperature of the solution does not rise, and the solution turns dark blue. The divalent copper salt solution is heated to a boil, and 10% glucose solution is added until the blue color disappears, and red cuprous oxide is precipitated. Then put it in 1L of cold water, let it stand for about 15 minutes, discard the supernatant liquid; add water and stir, after decantation, filter with a Buchner funnel; wash the precipitate twice with 15mL water, and then wash it with ethanol three times, And finally dry in an air bath.
6. Direct oxidation of metallic copper: Use platinum wire to hang metallic copper in a vertical tubular electric furnace, and heat it at 1000°C for 24 hours in a nitrogen atmosphere containing 1% (volume fraction) of oxygen to obtain cuprous oxide. Or the stoichiometric mixture of metallic copper and copper oxide is enclosed in a vacuum tube and heated at 1000° C. for 5 hours to react to obtain cuprous oxide.
Applications of Cuprous Oxide Cu2O powder:
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. Cuprous oxide is commonly used as a pigment, fungicide and antifouling agent in marine coatings. Besides that, what is cuprous oxide used for?
1. Suitable for pesticides.
2. Suitable for antibacterial fibers and clothes.
3. Cuprous oxide is also suitable for agricultural fungicides.
4. As an antiseptic, it is suitable for ship primers to prevent pollution and microorganisms.
5. Used in the manufacture of various copper salts and analytical reagents.
6. Used as a catalyst for organic synthesis.
