Description
What’s the Molybdenum disilicide(MoSi2) heating element?
Molybdenum disilicide(MoSi2) heating element is one resistance heating component made from MoSi2 or as the basic material. When it’s heated to high temperature under the oxidizing atmosphere, one dense MoSi2film will be formed on its surface to protect the element against oxidizing further. Therefore, the element has unique anti-oxidation property under high temperature atmosphere. The highest temperature can reach 1800°C, the applicable temperature is between 500-1700°C.
Applications: It can be used as heating elements of industrial high-temperature furnace, like ceramics, magnetic materials, glasses, metallurgy, refractories etc.
Electric Property
1. Resistance Property
The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, the element resistance generally doesn’t change with the service life, so the old elements can be used with the new elements together.
2. Surface Load
Choosing element surface load based on furnace structure, temperature as well as atmosphere, is the key of optimizing element service life. The below picture shows the relationship among the furnace temperature, element temperature and surface load under the circumstance that thermal element radiation is not hindered. The shadow part is for common surface load and temperature range.
Recommend Surface Load
Furnace Temp(°C) 1400 1500 1600 1650 1700
Surface load of hot zone(w/cm2) <18 <15 <12 <10 <8
