How do you define it? Molybdenum Silicide ? Molybdenum Disilicide is an organic compound with the chemical composition MoSi2. It is a gray metallic liquid. Although insoluble in many acids, it is soluble in hydrofluoric as well as nitric. Both the radii of these atoms do not differ much, the electronegativities of both atoms is relatively close and their properties are similar to that of ceramics or metals. Molybdenum Disilicide is an electricallyconductive material. A passivation layer made of silicon dioxide at high temperatures can be placed on the surface to stop further oxidation. It can be used as a high temperature antioxidation coating material, integrated electrode films and structural materials.
Molybdenum Siicide:
MoSi2 (intermediate phase) is the most silicon-rich in the MoSi binary alloy system. This is a Dalton-type, intermetallic compound having a fixed structure. This high-temperature material has great performance because of its dual qualities as a metal and ceramic. Excellent high temperature oxidation resistance. It can withstand temperatures up to 1600 degrees Celsius, equivalent to SiC. MoSi is soft, and can be described as a metal. MoSi is used primarily as an integrated circuit heating element, and for high-temperature anti-oxidation coatings.
MoSi2 consists of silicon and molybdenum bonded with metal bonds. In MoSi2, silicon and silicon are also bonded via covalent bonds. Molybdenum Disilicide is a gray, tetragonal crystal. It is not soluble or soluble with common mineral acids such as aqua regia, but it can be dissolved in mixed acids of hydrofluoric and nitric acids. It can be used to heat elements in high-temperature (1700), oxidizing environments due to its high resistance against high-temperature oxygenation.
An oxidizing atmosphere forms a protective layer on the dense quartz (SiO2) surface. It is used to stop the continuous oxidation and oxidation molybdenum diicide. SiO2 fused with SiO2 at 1710degC is what forms a protective coating. The action of expanding its surface causes it to lose its protective power. The oxidant acts on the element and forms a protective coating. The element can not be used at temperatures between 400 and 700 degrees C for very long times due to its strong oxidation.
