A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.
The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.
Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.
The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.
The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.
Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.
The prices of other commodities like the MoSi2 Powder are also expected to be influenced.
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.

Applications of Molybdenum Silicide MoSi2 Powder
MoSi2 is widely used in heating elements. Molybdenum disilicide heating elements can be used at temperatures up to 1800°C for electric furnaces used in laboratories and production environments in glass, steel, electronics, ceramics, and for heat treatment of materials. Although these components are brittle, they can operate at high power without aging, and their resistivity does not increase with operating time.

Russia is a major supplier of industrial metals such as nickel, aluminium and palladium. Russia and Ukraine are both major wheat exporters, and Russia and Belarus produce large amounts of potash, an input to fertiliser. The price and market of the MoSi2 Powder will fluctuate under its influence. Prices of these goods have been rising since 2022 and are now likely to rise further because of the Russia-Ukraine conflict.
