Introduction to Molybdenum Silicide MoSi2 Pulp Molybdenum silicide In 1906, it was discovered. In different circumstances, molybdenum, silicon, and molybdenum may form molybdenum trisilicides (Mo3Si), Molybdenum pentasilicates (Mo5Si3) and molybdenum dilicates (MoSi2). Molybdenum trisilicide (MoSi2) – a Dalton type intermetallic compound – is the most important. A crystal combination of atomic elements in the structure of MoSi2 shows that metal and covalent bonds coexist. It also has exceptional high-temperature essential features.
Molybdenum Disilicide It is an organic compound. The chemical formula for MoSi2 is gray metal solid. Although insoluble in many acids, it is soluble in nitric and hydrofluoric acids. Both types of atoms are similar in their radii as well as electronegativity. This is comparable to that found in metal and ceramic. Molybdenum Disilicide The surface is electrically conductive and, at high temperatures, forms a silicon dioxide passivation layer to protect it from further oxidation.
This material can be used as an integrated electrode film, high-temperature oxide-resistant coating, electrical heating elements, structural materials and composite reinforcement. It also wear-resistant, wear-resistant, ceramics and in other bonding areas.

Molybdenum Siicide MoSi2 MoPowder’s Physicochemical Characteristics
MoSi2 refers to a form of intermediate phase that contains the highest amount of silicon in the Mo–Si binary alloy system. This is a Dalton type intermetallic compound having a fixed structure. The material is high-temperature and has great performance. It has both the characteristics of ceramic and metal. High-temperature oxidation resistance and resistance to temperature up 1600; SiC equivalent. Moderate density (6.24%g/cm3). Low thermal expansion coefficient (8.10-6K-1). Good electric conductivity. Higher brittleness and ductile transition temperatures (1000), below that of ceramics. This soft plastic is metallic-like. MoSi2 is used primarily as an integrated circuit, heating element, high temperature oxidation resistant coating and high-temperature structure material.
MoSi2 consists of silicon and molybdenum bonded with metal bonds. While silicon and silicon are both bonded using covalent bonds, silicon and molybdenum are bonded through covalent bonds. Molybdenum is a grey tetragonal disilicide. Although insoluble in all mineral acids (including aqua-roya), it is soluble in hydrofluoric acid mixed and nitric. It can also be used as a high-temperature (1700) heat element for oxidation atmosphere.
An oxidizing atmosphere forms a protective coating on dense quartz glass (SiO2) that has been heated to high temperatures. This prevents continuous oxidation. SiO2 protective layer is created when the temperature at which the heating element heats is above 1700. It is thickened to the melting point 1710, and then fused with SiO2 in molten droplets. Due to its surface-extending ability, the protective film loses its protective power. The protective film is formed again when the element is continuously exposed to the oxidant. Due to the high oxidation rate at low temperatures, this element can’t be used long at 400-700.
