The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the copper oxide?
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.

Albemarle, the world's largest lithium producer, said it would have to close its plant in Langelsheim, Germany if the EU designated lithium as a hazardous material. The European Commission is currently evaluating a proposal by the European Chemicals Agency (EHCA) to classify lithium carbonate, lithium chloride, and lithium hydroxide as hazardous to human health.
As a result, Albemarle will no longer be able to import lithium chloride, its main raw material, putting its entire plant in Langelsheim at risk of closure, Albemarle chief financial Officer Scott Tozier said. According to Tozier, the plant has annual sales of about $500 million and a forced closure would have a significant impact on Albemarle's operations.
Industry sources said that listing lithium as a hazardous substance would place an additional burden on the copper oxide, please feel free to contact us and send an inquiry.
