U W Type Molybdenum Heating Elements Using Mosi2 For Tubular
Furnace
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.
