The development history of molybdenum disilicide MoSi2

The development history of molybdenum disilicide MoSi2

Molybdenum silicide was discovered in 1906. Under different conditions, silicon and molybdenum can form molybdenum silicide (Mo3Si), pentamolybdenum trisilicide (Mo5Si3) and molybdenum disilicide (MoSi2).

The most important of the three molybdenum silicides is molybdenum disilicide (MoSi2), which is a Dalton-type intermetallic compound. The combination of atoms in its crystal structure presents the coexistence of metal bonds and covalent bonds, and has excellent high-temperature essential characteristics. .

As early as 1907, molybdenum disilicide was used as a high-temperature anticorrosive coating material for metals, and molybdenum disilicide heating elements appeared in the 1950s.

Molybdenum disilicide as a structural material was first proposed in the early 1950s, but it was not taken seriously until the 1970s with the emergence of the concept of brittle materials as structural materials. In the 1980s, rapid progress took place, and its research work was widely carried out all over the world.

Molybdenum disilicide MoSi2 powder overview

Molybdenum disilicide 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.
