The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on molybdenum disilicide.
Molybdenum disilicide formula is MoSi2. Molybdenum disilicide is a kind of molybdenum silicon compound, and it is also known as molybdenum silicide. Molybdenum disilicide molecular weight is 154.13.
Because the radius of the two atoms is not much different, and the electronegativity is relatively close, it has similar characteristics to metals and ceramics. The melting point is as high as 2030 ℃ and has electrical conductivity, which can form a passivation layer of silicon dioxide on the surface to prevent further oxidation at high temperature. Its appearance is gray metal color, which is derived from its square α-shaped crystal structure. it also has a hexagonal but unstable modified crystal structure. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid.
What is molybdenum disilicide used for?
Molybdenum disilicide is used in high temperature anti-oxidation coating materials, electric heating elements, integrated electrode films, structural materials, composite reinforcement materials, wear-resistant materials, structural ceramic bonding materials and other fields.
Energy chemical industry: electric heating elements, high temperature heat exchangers for atomic reactor devices, gas burners, high temperature thermocouples and their protective tubes, melting container crucibles (for smelting sodium, lithium, lead, bismuth, tin and other metals).
Microelectronics industry: MoSi2 and other refractory metal silicide Ti5Si3,WSi2,TaSi2 are important candidates for gate and interconnection films in large-scale integrated circuits.
Aerospace industry: as a high-temperature antioxidant coating, especially as a material for turbine engine components, such as blades, impellers, burners, tail nozzles and seals.
Automotive industry: turbocharger rotors, valve bodies, spark plugs and engine parts for automotive turbine engines.
What is MoSi2 heating element?
MoSi2 heating element is a kind of high-density material, which is composed of molybdenum disilicide and silica self-formed glaze. It can be used at the furnace temperature of 1800 ℃. These components have a long service life.
MoSi2 heating element is a special material, which has the best properties of ceramic and metal materials. It is as resistant to corrosion and oxidation as ceramic materials and has a low thermal expansion rate. Like metal materials, it also has good thermal conductivity and electrical conductivity. Thermal shock has no effect on the element, as a heating element, because of its strength, it can withstand many years of service.
MoSi2 resistivity increases with temperature. When connected to a constant voltage, the element obtains high power at a lower temperature, and the power decreases gradually with the increase of temperature, thus shortening the time for the furnace to reach the working temperature. However, with the decrease of the power of the element, the possibility of overheating is also reduced.
MoSi2 heating element resistance will not age even if exposed to high temperature during operation.
In addition, MoSi2 has very high chemical resistance, so it can be used in most furnace atmospheres. The most favorable conditions for MoSi2 are oxidation atmosphere, such as carbon dioxide, air and water vapor. However, MoSi2 elements also tend to operate well in carburizing, reduction, and neutral atmosphere.
