Chromium Oxide Coatings

Europe's largest economy, Germany, recently activated an emergency plan to manage gas supplies that the natural gas could be rationed if supplies are disrupted or disrupted by a stand-off over Russian demands to pay for fuel in rubles.  

German Vice-Chancellor, minister of economy and climate protection, said Germany's gas supplies were secure for now, but he urged consumers and businesses to reduce consumption, saying "every kilowatt of electricity counts." 

Germany's gas network regulator can ration gas if supplies run short. Plants would be the first to be affected. Special treatment will be provided to private families, hospitals, and other important institutions.  

Half of Germany's 41.5 million households use natural gas for heating, and industry consumption accounts for a third of the country's 100 billion cubic meters of gas demand in 2021.  

The price of many energy and commodities like the chromium oxide could be affected.


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 secretary of Ukraine's National Security and Defense Council said the US arms lease bill to Ukraine has not yet been implemented. This is still in the process and could start from July to September 2022, he said. The approval of this bill is a very positive decision for Ukraine. Aid to Ukraine through lend-lease will eventually come, the question is when.  

In an effort to speed up the supply of weapons to Ukraine, President Joe Biden signed a defense lend-lease bill for Ukraine at the White House on May 9.


Nippon Steel, JFE Steel, and Kobe Steel will work together to develop a steel-making process that uses hydrogen to reduce carbon dioxide emissions without using blast furnaces. Small test furnaces will be built at Nippon Steel's Hwazaki Research and Development Center (Kamiki city, Ibaraki Prefecture) and JFE's East Japan Steel In Chiba (Chiba City). The two test furnaces, which will be operational by 2024-25, will confirm whether ore with high levels of impurities can also operate smoothly.
