European Commission President Ursula von der Leyen recently called on India and other countries to support sanctions against Russia over the Ukraine incident. At The Raisina Dialogue forum, von der Leyen said, "We earnestly appeal to all members of the international community to support our efforts to achieve lasting peace."
Von der Leyen says countries around the world that have been suffering from the virus for two years must now deal with higher food, energy, and fertilizer prices. What is happening in Ukraine will not only determine the future of Europe, but also have profound implications for the rest of the world.
Because of the Russia-Ukraine conflict, the prices of many other commodities like the MoSi2 Powder are expected to continue to rise in the future.
About Molybdenum Silicide MoSi2 Powder:
MoSi2 is an intermetallic compound, molybdenum silicide is a refractory ceramic, mainly used for heating elements. It has a medium-density, a melting point of 2030 ° C, which is electrically conductive. At high temperatures, it forms a passivation layer of silica to protect it from further oxidation. The thermal stability of MoSi2 and the thermal stability of its high radiation make such materials and high radiation coatings in thermal shields from the atmosphere as they are used next to WSI2. MoSi2 is a material with a four-square crystal structure (α-modified) gray metal; its β-modification is hexagonal and unstable. It is insoluble in most acids but is dissolved in nitric acid and hydrofluoric acid.
Although MoSi2 has excellent oxidation and high Young's modulus at temperatures above 1000 ° C, it is brittle at lower temperatures. Moreover, at 1200 ° C or more, it will lose creep resistance. These properties are limited to their structural materials but can be shifted by using it as a composite with another material.
Molybdenum disilicide (MoSi2) is a promising candidate material for high-temperature structural applications. It is a high melting point (2030 C) material with excellent oxidation resistance and a moderate density (6.24 g/cm3). However, low toughness at low temperatures and high creep rates at elevated temperatures have hindered its commercialization in structural applications. Much effort has been invested in MoSi2 composites as alternatives to pure molybdenum disilicide for oxidizing and aggressive environments. Molybdenum disilicide-based heating elements have been used extensively in high-temperature furnaces. The low electrical resistance of silicides in combination with high thermal stability, electron-migration resistance, and excellent diffusion-barrier characteristics is important for microelectronic applications.

Chemical Composition of Molybdenum Silicide MoSi2 Powder:
How is Molybdenum Silicide MoSi2 Powder produced?
Molybdenum disilicide and MoSi2-based materials are usually made by sintering. Plasma spraying can be used to produce dense monoliths and composite forms. The material produced by this method may contain a certain proportion of β-MoSi2 due to its rapid cooling.
Applications of Molybdenum Silicide MoSi2 Powder:
Molybdenum disilicide heating elements can be used for temperatures up to 1800 ° C, in electric furnaces used in laboratory and production environment in the production of glass, steel, electronics, ceramics, and in heat treatment of materials. Molybdenum disilicide is used in microelectronics as A Contact Material.
MoSi2 is a conductive silicide that has an oxidation property due to a stable silica layer on its surface at a high temperature.
Although the top MoSi2 element can operate at temperatures up to 1800 ° C, the material is very brittle, which may suffer serious creep during use. However, they have process advantages because they can work under high electrical loads without aging, and will not exhibit increased resistivity during use. They have antioxidant properties in air, oxygen and oxygen-rich atmosphere.
Moreover, they can be used with ammonia, nitrogen, hydrogen, a rare gas, and limited vacuum, but due to the failure of the protective oxide layer, the operating temperature and life can be reduced.
MoSi2 elements are ready-made elements and can be made into a bending or straight form of a variety of sizes. These elements are mainly used in production furnaces and laboratory furnaces in ceramics, glass, steel, electronics and heat treatment industries.
Amazingness and high-temperature elasticity make MoSi2 a very promising material for high-temperature applications such as gas turbine engines. Many researchers strive to improve high temperature creep resistance and low-temperature ductility. However, there are no commercially available composites with all preferred features.

Molybdenum Silicide Health & Safety Information
Recently, the Turkish government announced that the Turkish President has signed a presidential decree to provide incentives for its Black Sea gas field development projects, including tax exemptions and other preferential measures.
With a fixed investment of 145.1 billion Turkish lira ($10 billion), the project will employ 1,018 people and produce 14 billion standard cubic meters of gas per year, the decree reads. The incentives involved include tariff and VAT exemptions, as well as a range of tax cuts.
In June 2021, Turkish drill ships discovered 135 billion cubic meters of natural gas in the Sakaria field in the Black Sea, bringing Turkey's total gas discoveries in the region to 540 billion cubic meters.
Turkey imports almost all of its annual gas consumption of about 50 billion cubic meters.
Except for natural gas, the supply and prices of many other MoSi2 Powder will continue to be influenced by international situations.
