Introduction to Molybdenum Silicide MoSi2 Pulp
In 1906, it was discovered. In different circumstances, silicon and molybdenum may form molybdenum trisilicide, molybdenum pentasilicate, and molybdenum silicate (Mo3Si2). Molybdenum trisilicide (MoSi2) – a Dalton type intermetallic compound – is the most important. The excellent high-temperature essential qualities of the atomic combination found in its crystal structure show coexistence between metal bonds and covalent bond.
It is an organic compound. The chemical formula for MoSi2 is gray metal solid. Although insoluble in most acids it is soluble in nitric and hydrofluoric acids. Both types of atoms have the same radii as well as electronegativity. This is similar to metal or ceramic.
The surface is electrically conductive and at high temperatures forms an oxide layer of silicon dioxide to protect it from further oxidation.
It can be used in high-temperature, oxidation-resistant coatings, electric heating elements and integrated electrode films, as well as structural materials, composite reinforcements, wear-resistant materials and other fields.
Molybdenum silicicide MoSi2 MoPi2 Powder – Physical Properties
MoSi2 refers to a type of intermediate phase that has the highest silicon content in Mo-Si’s binary alloy system. This is a Dalton-type intermetallic composition with a fixed structure. It is a type of high-temperature material that exhibits both ceramic and metal properties. High-temperature oxidation resistance and oxidation resistant temperature up to 1600 with SiC equivalent; Moderate densities (6.24g/cm3). Low thermal expansion coefficient (8.10-6K-1); Excellent electric conductivity. Higher brittleness and ductile transition temperatures (1000), below the hardbrittleness of ceramics. It is a metal-like soft material above 1000. MoSi2 is used primarily as a heating element, integrated circuits, high temperature oxidation-resistant coating and high-temperature structure material.
MoSi2 consists of silicon and molybdenum bonded with metal bonds. While silicon and silicon can be bonded by covalent bond, silicon and molybdenum are bonded via metal bonds. Molybdenum disilicide can be described as a gray tetragonal stone. It is insoluble with most mineral acids (including aqua-roya), but is soluble and can be used to heat an oxidation atmosphere at high temperatures (1700).
An oxidizing atmosphere forms a protective layer on the surface quartz glass (SiO2) that has been heated to high temperatures. This prevents continuous oxidation. SiO2 protective layer is formed when the temperature of heating element exceeds 1700. It thickens at the melting point 1710 and is fused with SiO2 to create molten dropslets. Its surface-extending ability causes it to lose its protective properties. The protective film is formed again when the element is continuously exposed to the oxidant. Due to the high oxidation at low temperatures, this element can’t be used for extended periods of time at 400-700.

Molybdenum Siicide MoSi2 Powder Applications
MoSi2 can be found in many heating elements.
Heating elements with molybdenum diilicide
Can be used at temperatures as high as 1800 degrees Celsius for electric furnaces. These furnaces are used in laboratories, production environments in glass, steel and ceramics. They also can be used for heat treating of materials. These components are not only brittle but can also operate at high power and without aging. Their resistivity doesn’t increase with time.
