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 manganese silicide, manganese silicide overview, manganese silicide application, manganese silicide suppliers, manganese silicide price are still very uncertain.
Manganese Silicide Overview
Manganese silicide, molecular formula: MnSi2, English name: manganese disilicide, inorganic compound, gray octahedral crystal, density: 5.24g/mL, soluble in hydrofluoric acid, alkali, insoluble in water, nitric acid, sulfuric acid.
Manganese silicide synthesis method
2 g (0.036 mol) manganese, 2 g (0.071 mol) silicon and 10 g (0.16 mol) copper are placed in small pieces in a 10 mL Al2O3 crucible and placed in a quartz ampoule with one end open. After evacuation and sealing, the ampoules are placed in a high-temperature furnace of carbon silicon rods. The temperature was raised to 1200°C within 12h, and then lowered to 500°C at a rate of 10°C/h. The ampoule is removed, cooled, and inserted into a thicker diameter rubber tube, breaking the ampoule so that the metal ingot can be safely removed. The copper-rich Cu—Mn—Si matrix was dissolved in 8 mol/L nitric acid, and the octahedral crystals remained. These crystals were washed with water and dried to obtain MnSi2 crystals with an edge length of 2 mm.
Manganese Silicide Properties and Stability
Soluble in hydrofluoric acid and alkali, insoluble in water, nitric acid and sulfuric acid.
Application of manganese silicide MnSi2 powder
Due to its unique physical and chemical properties, manganese disilicide (MnSi2) has been successfully used in materials and photovoltaic materials in the fields of complementary metal oxide semiconductor elements, thin film coatings, bulk structure elements, electric heating elements, thermoelectric elements, etc.
Using manganese silicate thermoelectric conversion material, the power factor of power generation capacity is 2.4mW/K2m, which is about twice the original power. Manganese disilicide (MnSi2) is also expected to convert waste heat at 300-700°C and other waste heat into electricity for use in engines and industrial furnaces and in the field of industrial furnaces for high-power thermoelectric power generation modules.
