MoSi2 Heater Rod Introduction:
MoSi2 heating elements is a kind of resistance heatingelement made from Molybdenum Disilicide.
It can be used in air and various gases environments. Working temperature of MoSi2 heating element is 1300C to 1800C. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high temperature low distortion, easy installation and maintenance, excellent chemical stability, which has been widely used as heaters in high temperature furnaces and kilns of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture and chemical industry field.
Types of MoSi2 Heating Elements
1. According to temperature: 1700C and 1800C
2. According to Shape: U, W, I, UL, WL, Spiral types
It must be pointed out is that the MoSi2 heater cannot be used in the temperature between 400℃ to 700 ℃ for long time. Otherwise, the element will be pulverized because of the strong low-temperature oxidation.
Resistance characters of MoSi2 heater
MoSi2 elements have good resistance characteristic, so it is an ideal heating material to replace traditional heating elements.
At room temperature, its resistivity is very low, with the increase of temperature, the resistance increases sharply. The advantages of heating up fast and low power consumption are obvious.
In normal operating circumstances, the resistance of the element is constant, so the old and new components can be mixed.
