What is Molybdenum disilicide powder? The appearance of molybdenum di-silicate is a gray metallic solid with a melting point of about 2030°C and a density of about 6.26 g/cm3, which is insoluble in most acids except nitric and hydrofluoric acid. It has a low thermal expansion coefficient, good electric thermal conductivity, dual characteristics of metal and ceramics, high-temperature oxidation resistance, and other characteristics. At temperatures greater than 1000℃, its surface can form a silica passivating layer to prevent further oxidation, with an extremely high Young's modulus. Still, it is brittle at low temperatures and loses creep resistance over 1200℃. According to different shapes, MoSi2 heating components can be divided into straight rod, U-shaped rod, three-phase rod, gun rod, five-segment rod, groove rod, single-threaded rod, double-threaded rod, and other specifications.
Main uses of Molybdenum disilicide powder Molybdenum can be used in high-temperature oxidation resistance coating materials, electric heating elements, integrated electrode film, structural materials, composite reinforced materials, wear-resistant materials, structural ceramic connection materials, and other fields. Heating components made from molybdenum powder are mainly used in glass, steel, electronic components, ceramics, and other products in electric furnaces; molybdenum powder can also be used as a surface coating material for high-temperature resistant ceramics, thermocouple vacuum protection pipe or evaporation appliance. Production of molybdenum Molybdenum disilicate can be obtained by the direct reaction of Mo powder and Si powder or by the oxide reduction reaction of Mo. Two silicon molybdenum parts can be made by cold pressure sintering or hot pressure system. If the molding method is formed, the batter, starch, glycerin, and so on can be used as a binder. When forming by the extrusion method, 2% to 4% dextrin was added to make the binder. MoSi2 The products were fired at 1500~1900℃. Suppose a small amount of SiO2 is added to the disilicate molybdenum powder. In that case, SiO2 melting will form a protective film on the surface of the molybdenum disilicate products at high temperatures, increasing the working temperature of molybdenum this silicate to 1710~1780℃. The mechanical properties of cold-pressure sintering products are poor. At hot pressure, the temperature is 1550~1750℃, and the pressure is 9.8~78.5MPa. The mixture of molybdenum and alumina. Price of Molybdenum disilicide powder The different price of Molybdenum disilicide powder purity is also different.
