Difference Between Cu2O and CuO
Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.
Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine. Even before the war, the aluminium market was suffering from long waiting times and weak demand.
For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases. Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020. This was mainly due to a slowdown in new orders and copper oxide are expected to increase in the future.
What is Cu2O?
Cu2O or cuprous oxide is an oxide of univalent copper, usually in the form of brick red or reddish-brown crystals and powders. Cu2O is rich in nature, mainly in the form of chalcopyrite.
Cu2O is insoluble in water and organic solvents, but soluble in dilute hydrochloric acid, dilute sulfuric acid and ammonium chloride solution. Cuprous oxide is relatively stable at room temperature and dry conditions, and can be oxidized to CuO only after heating for a long time or in moist air.
What is Cu2O used for?
Cuprous oxide is used to make a ship bottom antifouling paint (killing low-grade marine animals). Used as fungicides, colorants for ceramics and enamels, red glass stains, and materials for making various copper salts, analytical reagents and rectifier electroplating in the electrical industry, fungicides for crops and rectifiers, etc. Cuprous oxide is also often used as a catalyst for the synthesis of organic compounds.
In recent years, Cu2O has attracted more and more attention, because Cu2O is a p-type semiconductor material with excellent properties, and has the advantages of non-toxic, easy to prepare, good chemical stability, etc. It has special optical and magnetic properties and has potential applications in the fields of photocatalysis and photoelectric conversion. The band gap is about 2.17 ev, which can absorb visible light for photocatalysis and photoelectric conversion in theory, and the highest photoelectric conversion efficiency can reach 18%.
Because of the excellent performance and promising application potential of Cu2O, researchers are committed to the preparation of Cu2O with various morphologies and structures, such as conventional films, porous films, micro-nanostructure films, nanowires and nanowires and so on.
What is CuO?
CuO or cupric oxide is a black oxide of divalent copper. Slightly bisexual and slightly hygroscopic. Copper oxide is insoluble in water and ethanol, easily soluble in acid, stable to heat, and decomposed into oxygen at high temperature.
What is CuO used for?
Copper oxide can be used as organic synthesis catalyst, analytical reagent (for nitrogen determination), oxidant, catalyst and petroleum desulfurizer, and can also be used for the determination of carbon in organic compounds.
Used as a colorant for glass, enamel and ceramic industry, anti-wrinkle agent for paint and polishing agent for optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in rayon manufacturing industry and as a desulphurizer for grease. It is used as the raw material for the manufacture of other copper salts and for the manufacture of artificial gems.
Difference Between Cu2O and CuO
Cuprous oxide Cu2O and copper oxide CuO are compounds of the chemical element copper. These oxides contain copper in different oxidized states. In addition, there is a +1 oxidation state in cuprous oxide and a +2 oxidation state in copper oxide.
The main difference between cuprous oxide and copper oxide is that cuprous oxide is crimson while copper oxide is black.
Another difference between cuprous oxide and copper oxide is that cuprous oxide naturally exists in the form of reddish minerals, chalcopyrite, while copper oxide exists in the form of mineral pyrite.
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

Indonesia plans to increase the content of palm oil-based fuel in biodiesel from 30% to 35%, from B30 to B35, starting from July 20, a senior official from Indonesia's Ministry of Energy said this evening, according to Reuters.
Indonesia, the world's largest palm oil producer, imposed a three-week export ban in May to control domestic cooking oil prices, leading to an increase in palm oil stocks. At present, the authorities are considering reducing the export tax on palm oil to stimulate exports.
Indonesia's Ministry of Energy said that while implementing B35, the ministry will also launch road tests of B40 fuel. Indonesia's senior cabinet minister Luhut Pandjaitan estimates that if Indonesia implements B40, the domestic market may absorb an additional 2.5 million tons of palm oil.
A German government spokesman confirmed that Germany has always wanted Canada to release parts of the "Nord Stream 1" natural gas pipeline sent by Siemens for repair, and this request has received a "positive" response from Canada.
The "Nord Stream 1" natural gas pipeline is the main pipeline for Russia to transmit gas to Europe. At present, the gas output of " Nord Stream 1" has been reduced by 60% compared with the beginning of June, and this is an important time for Germany to store gas for the winter. The German government plans to increase its natural gas inventory to 90% of its gas storage capacity by November, compared with 62% now. Therefore, there is a great need for "Nord Stream 1" gas transmission to fill the inventory.
