According to statistics from China Chemical and Physical Power Supply Industry Association， China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year.
From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of chromium oxide, led by lithium-ion batteries, is expected to expand globally.
Chromium oxide (Cr2O3) is a kind of dark green powder with metallic luster and belongs to hexagonal or amorphous crystal. Cr2O3 melting point is 2265℃ ~ 2435℃ and Cr2O3 density is 5.2g/cm3. It is a neutral oxide.
Chromium oxide has good spraying process performance, its spraying process specification is wide, it is less sensitive to overheating during spraying, and the coating is not easy to crack when local overheating occurs. The spray coating is very dense and has high bonding strength with the substrate, so it is easy to be machined such as grinding and polishing.
However, the deposition efficiency of pure chromium oxide powder is low, which will increase the cost of the coating. The chromium oxide coating prepared by flame spraying or plasma spraying is dense and insoluble in acid, alkali and alcohol. After proper sealing treatment, the coating can be used in the environment with chemical corrosion medium.
Cr2O3 coatings properties
The chemical properties of plasma sprayed chromium oxide coating are very stable, insoluble in acid, alkali, salt and various solvents, excellent corrosion resistance to medium impregnation, high temperature erosion resistance to corrosive gases such as H2S and SO2, stable to atmosphere, fresh water, sea water and light, but soluble in hot sodium bromide solution. Chromium oxide coating has good hydrophilicity and a uniform water film is formed on the surface of the coating.
What are Cr2O3 coatings used for?
Cr2O3 coatings can be used as abrasive wear resistant coating, hard surface wear and erosion wear coating below 540℃, cavitation wear resistant coating, corrosion wear resistant coating for parts used in chemical media below 250℃ (need to be properly sealed), such as pistons, plungers, chemical machinery shafts, pump seals, wear-resistant rings, slide valves, cylinder linings, exhaust fans, polishing and polishing fixtures, etc. Fiber wear-resistant coating, such as guide wheel, friction wheel, roller roller of chemical fiber spinning machine, magnetic conductive and wear-resistant coating, such as tape recorder head, etc.
The sprayed Cr2O coating is dark dark green with strong covering ability and high and stable thermal emissivity in a wide range of off-line wavelengths. Commonly used in infrared radiation coating (such as electric heating pipe coating), high temperature magnetic conductive wear-resistant coating, etc.
Chromium oxide Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the chromium oxide in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the chromium oxide is predicted to see further improvement over the coming days.
