Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk MoSi2 Powder are still very uncertain.
Introduction to Molybdenum Silicide MoSi2 Powder
Under different conditions, silicon and molybdenum can form several different compounds, including trimolybdenum silicide (Mo3Si), pentamolybdenum trisilicide (Mo5Si3), and molybdenum disilicide (MoSi2), of which the most important is molybdenum disilicide (MoSi2).
Molybdenum disilicide is an inorganic compound, the chemical formula is MoSi2, gray metal solid.
Molybdenum silicide has a high melting point, low density, good thermal conductivity, good electrical conductivity and excellent high-temperature oxidation resistance, high elastic modulus, low thermal expansion coefficient, high strength, and good resistance to chemical corrosion and thermal shock resistance. MoSi2 is widely used in high-temperature heating element component materials and high-temperature oxidation resistance coating materials, is also the most development potential for high-temperature structural materials and wear-resistant materials.
Key Properties of Molybdenum Silicide MoSi2 Powder
High melting point
High modulus at high temperature
Excellent oxidation resistance

Applications of Molybdenum Silicide MoSi2 Powder
Molybdenum disilicide is used in the fields of high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode films, structural materials, reinforcement of composite materials, wear-resistant materials, bonding materials of structural ceramics,etc. Specifically, it can be used in:
1. Energy chemical industry: electric heating elements, high-temperature heat exchangers of atomic reactor device, gas burner, high-temperature thermocouple, and its protective tube, crucibles of melting utensils (used for melting sodium, lithium, lead, bismuth, tin, and other metals).
2. Microelectronics industry: MoSi2 and other refractory metal silicides Ti5Si3, WSi2, and TaSi2 are important candidate materials for lsi gate and interconnect thin films.
3. Aerospace industry: used as high-temperature oxidation-resistant coating materials. Especially as turbine engine components such as blades, impellers, burners, nozzles, and seals.
4. Automotive industry: automotive turbocharger rotor, valve body, spark plug, and engine parts.
What is the MoSi2 Heating Element?
Molybdenum disilicide heating element is a kind of high-density material composed of molybdenum disilicide and silicon dioxide self-forming glaze. The operating temperature can reach 1800℃. These components have a long service life.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the MoSi2 Powder will be influenced by that.
