What is Molybdenum silicide? Molybdenum silicide powder is an inorganic compound composed of one transition metal atom (both tungsten and molybdenum belong to transition metal elements) and two non-metallic silicon atoms. It is a black powder, named Molybdenum silicide powder in English, with a chemical formula of MoSi2, a molecular weight of 152.11, a purity of 99.9%, a square crystal structure, and a CAS number.
The main component of molybdenum silicide powder is 36%~38% of total Si(T.C), and the rest is molybdenum. Impurity content of MoSi2: free silicon (F.Si)0.1%, Fe0.03%, Al0.01%, N0.01%, C0.03%, O0.15%. Common particle sizes of MoSi2: 300 mesh, 400 mesh, 500 mesh, 3.5~2.6μm, 2.3 ~ 1.5 μ m. Characteristics of Molybdenum silicide Powder Molybdenum silicide is gray and metallic in appearance, with a melting point of about 2030°C and a density of about 6.26g/cm3. It is insoluble in most acids except nitric acid and hydrofluoric acid and has the characteristics of a low thermal expansion coefficient (8.1×10-6K-1), good electrothermal conductivity, dual characteristics of metal and ceramic, and high-temperature oxidation resistance. Specifically, at a high temperature greater than 1000℃, it can form a silicon dioxide passivation layer to prevent further oxidation, and it has a very high Young's modulus, but it is brittle at a low temperature, and it will lose its creep resistance in an environment exceeding 1200℃. Usesof Molybdenum silicide Powder Molybdenum silicide has conductivity, and a passivation layer of silicon dioxide can be formed on the surface at high temperatures to prevent further oxidation. It is used in the fields of high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode films, structural materials, reinforcing agents of composite materials, wear-resistant materials, connecting materials of structural ceramics, etc. The heating elements made of molybdenum silicide powder are mainly used in the production of glass, steel, electronic components, ceramics, and other products in electric furnaces. In addition, the substance can also be used as a surface coating material for high-temperature-resistant ceramics, thermocouple vacuum protection tubes, or evaporation devices. Price of Molybdenum silicide powder Molybdenum silicide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Molybdenum silicide powder. A large amount of large amount will be lower. The price of Molybdenum silicide powder can be found on our company's official website.
