Global MoSi2 Powder market trend 2024-2027 What is Molybdenum Silicide MoSi2 Powder? by Newsfgjiaju

Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the MoSi2 Powder, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and MoSi2 Powder industry, especially in Europe. The price of the MoSi2 Powder will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.

Introduction to Molybdenum Silicide MoSi2 Powder
Molybdenum silicide was discovered in 1906. Under different conditions, silicon and molybdenum can form molybdenum trisilicide (Mo3Si), molybdenum pentasilicate (Mo5Si3), and molybdenum disilicate (MoSi2). The most important one is the Molybdenum disilicide (MoSi2), which is a Dalton-type intermetallic compound. The atomic combination in its crystal structure shows the coexistence of metal bonds and covalent bonds, and has excellent high-temperature essential characteristics.
Molybdenum disilicide is an inorganic compound, the chemical formula is MoSi2, gray metal solid. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid. The two kinds of atoms have similar radii and electronegativity, which is similar to metal and ceramic.  Molybdenum disilicide is electrically conductive and at high temperatures forms a passivation layer of silicon dioxide on the surface to prevent further oxidation.
It can be applied as high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode film, structural materials, composite reinforcement, wear-resistant materials, structural ceramics, and other fields of bonding materials. 
 

Physicochemical Properties of Molybdenum Silicide MoSi2 Powder
MoSi2 is a kind of intermediate phase with the highest silicon content in the Mo-Si binary alloy system, and it is a Dalton-type intermetallic compound with a fixed composition. It has dual characteristics of metal and ceramic, and is a kind of high-temperature material with excellent performance. Good high-temperature oxidation resistance, oxidation resistance temperature up to 1600, and SiC equivalent; Moderate density (6.24g/cm3); Low thermal expansion coefficient (8.1×10-6K-1); Good electric conductivity; Higher brittle and ductile transition temperature (1000) below the hard brittleness of ceramics. Above 1000 it is metal-like soft plastic. MoSi2 is mainly used as heating elements, integrated circuits, high-temperature oxidation-resistant coating, and high-temperature structural material. 
In MoSi2, molybdenum and silicon are bonded by metal bonds, while silicon and silicon are bonded by covalent bonds. Molybdenum disilicide is gray tetragonal crystal. Insoluble in general mineral acids (including aqua roya), but soluble in nitric acid and hydrofluoric acid mixed acid, has good high-temperature oxidation resistance, can be used as high temperature (<1700) oxidation atmosphere work heating element. 
In an oxidizing atmosphere, a protective film is formed on the surface of dense quartz glass (SiO2) burned at a high temperature to prevent continuous oxidation. When the temperature of the heating element is higher than 1700, SiO2 protective film is formed, which is thickened at the melting point of 1710 and fused with SiO2 into molten droplets.  It loses its protective ability due to its surface-extending action. When the element is used continuously under the oxidant, it forms a protective film again. It should be noted that this element cannot be used for long periods at 400-700 due to strong oxidation at low temperatures.

The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry. In 2020, global revenue from the travel and tourism industry was estimated to drop from a forecasted 711.94 billion U.S. dollars to 568.6 billion U.S. dollars, representing a decrease of over 20 percent. The region predicted to see the highest decline in revenue was Europe, decreasing from 211.97 billion U.S. dollars in 2019 to roughly 124 billion U.S. dollars in 2020.
The downturn in tourism has caused the recession, and the weakening of the economy has also affected the market demand for MoSi2 Powder. Recently, however, the demand for MoSi2 Powder has increased, so contact us for the latest news on MoSi2 Powder.
