Whats so unique about Molybdenum disilicide powder
What is Molybdenum Disilicide Powder?The appearance
The gray metallic solid has a melting point around 2030degC, a mass density of 6.26g/cm3, and is insoluble with most acids except for nitric or hydrofluoric. Its properties include a low coefficient of thermal expansion, good electrical thermal conductivity and dual characteristics as metals and ceramics. The surface of the material can be coated with a silica-based passivating film at temperatures above 1000°C to prevent further corrosion. This layer has an extremely high Young’s modulus. It's brittle even at low temperatures, and it loses its creep resistance above 1200. MoSi2 can be divided according to its shapes into straight rods, U shaped rods, gun rods, five segment rods, groove rods, single threaded rods, double threaded rods and other specifications.
Molybdenum disilicide powder: Main applications
Molybdenum has many applications, including electric heating elements, composite reinforced material, wear-resistant products, structural ceramic connections materials, etc. Molybdenum-based heating components are widely used in electric furnaces for glass, ceramics, electronic components, and steel.
Production of Molybdenum
Molybdenum oxide can be reduced by Mo powder to produce molybdenum disilicate. By using either a hot or cold pressure system, two silicon-molybdenum parts are made. As a binder, you can use the batter, starch and glycerin if the molding technique is used. Dextrin, in the range of 2% to 4 %, was used to create the binder when forming using the extrusion technique. MoSi2 Products were fired from 1500 to 1900. Imagine that a small amount SiO2 was added to disilicate molybdenum. SiO2 melting forms a protective layer on the surface of molybdenum products disilicated at high temperature, increasing their working temperature to 17101780. Cold-pressure products have poor mechanical properties. When under hot pressure, temperatures range from 1550 to 1750 degrees Celsius, while pressures are 9.8 to 78.5 MPa. The mixture is molybdenum with alumina.
