Global Molybdenum disilicide MoSi2 powder market trend 2023-2030 Physicochemical properties and application of molybdenum disilicide MoSi2 by Newswrigleyfieldnews

The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the Molybdenum disilicide MoSi2 powder? 

Molybdenum disilicide MoSi2 powder overview

Molybdenum disilicide MoSi2 powder  is an inorganic compound with the chemical formula MoSi2, which is a gray metallic solid. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid. The radii of the two kinds of atoms are not much different, the electronegativity is relatively close, and they have properties similar to those of metals and ceramics. Molybdenum disilicide is conductive and can form a passivation layer of silicon dioxide on the surface at high temperatures to prevent further oxidation. It is used in high-temperature anti-oxidation coating materials, electric heating elements, integrated electrode films, structural materials, reinforcing agents for composite materials, wear-resistant materials, and connecting materials for structural ceramics.

Physicochemical properties of molybdenum disilicide MoSi2

Molybdenum disilicide MoSi2 is an 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. With the dual characteristics of metal and ceramics, it is a high-temperature material with excellent performance. Very good high temperature oxidation resistance, the oxidation resistance temperature is as high as 1600℃, which is equivalent to SiC; moderate density (6.24g/cm3); low thermal expansion coefficient (8.1×10-6K-1); good electrical and thermal conductivity Properties; higher brittle-to-ductile transition temperature (1000℃) below has ceramic-like hardness and brittleness. It is metal-like soft plasticity above 1000°C. MoSi is mainly used as heating elements, integrated circuits, high-temperature anti-oxidation coatings and high-temperature structural materials.

In MoSi2, molybdenum and silicon are connected by metal bonds, and silicon and silicon are connected by covalent bonds. Molybdenum disilicide is a gray tetragonal crystal. It is insoluble in general mineral acids (including aqua regia), but soluble in a mixed acid of nitric acid and hydrofluoric acid. It has good high temperature oxidation resistance and can be used as a heating element working in high temperature (<1700°C) oxidizing atmosphere.

In an oxidizing atmosphere, a protective film is formed on the surface of the dense quartz glass (SiO2) that burns at a high temperature to prevent continuous oxidation of molybdenum disilicide. When the temperature of the heating element is higher than 1700°C, a SiO2 protective film is formed, which fuses at a melting point of 1710°C, and merges with SiO2 into a molten drop. Because of the action of its surface extension, it loses its protective ability. Under the action of the oxidant, when the element is used continuously, it forms a protective film again. It should be noted that due to the strong oxidation at low temperatures, this element cannot be used for a long time in a temperature environment of 400-700°C.

Molybdenum disilicide MoSi2 powder application

Molybdenum disilicide MoSi2 is used in high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode membranes, structural materials, composite reinforcement materials, wear-resistant materials, structural ceramic connecting materials and other fields, and are distributed in the following industries:

1) Energy and chemical industry: MoSi2 is used as electric heating element, high temperature heat exchanger of atomic reactor device, gas burner, high temperature thermocouple and its protection tube, smelting vessel crucible (used for smelting sodium, lithium, lead, bismuth, tin and other metals) .

2) Microelectronics industry: MoSi2 and other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidates for large-scale integrated circuit gates and interconnections.

3) Aerospace industry: MoSi2 as a high-temperature anti-oxidation coating material, especially as a material for turbine engine components, such as blades, impellers, combustion chambers, nozzles and sealing devices, has been widely and in-depth Research and application.
