What is MoSi2 rod ?
Mosi2 heating element is a special product combined metal and ceramics. So it has the characteristics of silicon and molybdenum.
Molybdenum disilicide (MoSi2) is a refractory metal silicide that is primarily used as a heating element. In recent years, its potential for use as a structural ceramic has been recognised, as the material combines excellent oxidation resistance and high elastic modulus at elevated temperatures.
Under the oxidizing atmosphere, the maximum operating temperature of MoSi2 rod is 1800C, the resistance of the heating element of silicon molybdenum rod increases rapidly with the temperature increasing, and the resistance value is stable when the temperature is constant.Under normal conditions, the resistance of elements does not change with the service time, so the new and old elements can be mixed.
3.According to the structure, working atmosphere and temperature of the heating equipment, the correct selection of the surface load of the heating element is the key to the service life of the element.
It should be pointed out that element cannot be used for rather long time in 500-1700°C, or it will be powdered owing to the strong oxidizing action in low temperature.
