What is Cuprous Oxide Cu2O Used For?

Recently, the EU proclaimed new sanctions on Russia, including coal, timber, rubber, cement, and fertilizer, as well as high-end seafood Cu2O powder.

What is Cuprous Oxide Cu2O?
Cuprous oxide, the chemical formula is Cu2O, is a univalent copper oxide, bright red powder solid, almost insoluble in water, in acidic solution disproportionation into bivalent copper and copper elemental, gradually oxidized in wet air into black copper oxide. 
Cuprous oxide is commonly used as pigment, fungicide, and antifouling agent in Marine coatings. Rectifier diodes based on this material were used in industry as early as 1924, long before silicon became the standard. Copper oxide (I) is also responsible for the positive pink color of Benedict's test. 
What is Cupric and Cuprous Oxide? 
Copper is a red-orange metal with high conductivity to heat and electricity. It shares this ability with silver and gold because each of these elements has a "free-agent" electron that can negotiate chemical bonds with any available atom around it. All the other electrons are tightly bound to their group, but this one is susceptible to transfer. 
When copper is exposed to a water molecule (two hydrogens and one oxygen), this free electron is transferred to a neighboring oxygen atom, binding it into a single molecule. If only one copper atom is bound to the oxygen molecule, it is called copper oxide. If two copper atoms bond with one oxygen atom, it is cuprous oxide. Copper oxide is considered "fully oxidized" while cuprous oxide remains active.
The key to cuprous oxide is its active state, which makes it very effective as a fungicide.  It's still producing reactive oxygen, highly reactive molecules. These are unstable molecules that can cause damage to cellular structures.
What is Cuprous Oxide Used For? 
Antifouling paint for ships and ship bottoms; It is an effective control of corrosion. 
Paint for glass and porcelain.
Used as p-type semiconductor material for the manufacture of photocells for light meters and for the manufacture of rectifiers. 
Used as a fungicide and seed dressing agent.
Cuprous oxide is commonly used as a catalyst in the production of other chemicals. Used for manufacturing zinc chloride, ferrous chloride, etc. It is also used as a UV absorber in surface treatment products.
Cuprous oxide is one of the most common oxides in batteries, accounting for 9% to 15% of all batteries. It is also used in metal production, construction and construction, and in the production of plastics and other organic compounds. It is an ingredient in some paints and is used as an oxidant in many metal plating processes.
Used in industrial and construction industries as ultra-high purity reagents, catalysts and effective preservatives. It is particularly suitable for manufacturing and process control, as well as the construction industry. It is also used in water treatment, particularly for purifying water to remove dissolved particles and for polymerization of specific polymers. 
Used as a catalyst in metallurgy, the process is important for steel production. Catalysts act as reducing agents in the oxidation of iron.
Used as pigments and flame retardants, and as a flux in metal smelting.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".

The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.  

The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.

The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.

Affected by several factors, the supply of the Cu2O powder is erratic and thus its prices are expected to go higher in the future.
