Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Iron Disilicide.
Iron disilicide FeSi2 powder overview
Iron disilicide is an inorganic silicon compound with a molecular formula of FeSi2 and a molecular weight of 119.975. It is a gray powder, odorless, tetragonal crystals.
How is iron disilicide FeSi2 powder produced
A new catalytic material of supported silicide and iron silicide was successfully synthesized by the direct silicide method. The supported precursor and ferric oxide were successfully eliminated by co-precipitation, and then the precursor preparation was reduced to 3 h. Different phases of silicide-supported iron silicides were prepared under a hydrogen atmosphere at 400 °C and passed into a SiH4/H2 gas mixture at a suitable temperature for 15 min. The method has the advantages of small particle size, large specific area, strong sulfur resistance, and good catalytic activity and stability in the hydrodesulfurization reaction of mono-dibenzothiophene, and has potential application value.
Application of iron disilicide FeSi2 powder
Iron disilicide is used as a catalyst for hydrogen catalytic oxidation and methanation.
Iron disilicide is used as a deoxidizer for flux, humidity sensors, FeSi2 thermocouples and thermoelectric solar cells.
Iron disilicide is used in a variety of photovoltaic applications, such as lithium-ion batteries, light-emitting diodes (LEDs), and solar cells.
Iron disilicide price
The price of iron disilicide will fluctuate randomly due to factors such as Iron Disilicide will continue to be influenced by international situations.
