1700°C W Type Silicon Molybdenum Rods For Electric Furnaces

Product Description
 

Silicon molybdenum rod resistive heating element is a kind of resistance heating element with high temperature resistance and oxidation resistance made of molybdenum disilicide. When used in high-temperature oxidizing atmosphere, like other Si based high-temperature resistant materials, MoSi2 surface will rapidly form a bright and dense quartz (SiO2) glass film under high temperature and oxygen atmosphere, which can protect the inner layer of silicon molybdenum rod from further oxidation. Therefore, silicon molybdenum rod elements have unique high-temperature oxidation resistance.

In oxidizing atmosphere, the highest service temperature is about 1700℃, and the resistivity of MoSi2 increases rapidly with the increase of temperature.Under normal conditions, the resistance of the element does not change with the length of service, so the new and old silicon molybdenum rod heating element can be used in a mixture.

Due to the product specifications and models, the price is different, the price is not the actual price, do not directly auction.

Precautions for silicon molybdenum rod
1. The silicon molybdenum rod heating element should not be used within the temperature range of 400 ° C to 700 ° C, because under such unfavorable conditions, the element will undergo low-temperature oxidation and damage the element.
 
2. The silicon molybdenum rod heating element is suitable for use in air and neutral atmosphere. Reducing atmosphere such as hydrogen will damage the protective layer, and chlorine and sulfur vapor will directly damage the element.
