What is silicon molybdenum rod
Jan. 13, 2021
Silicon molybdenum rod resistive heating element, made on the basis of molybdenum disilicide, resistant to high temperature and oxidation. When used in a high-temperature oxidizing atmosphere, a bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon-molybdenum rod from oxidation. The silicon-molybdenum rod element has unique high-temperature oxidation resistance.
In an oxidizing atmosphere, the maximum operating temperature is about 1700°C, and the resistivity of MoSi2 increases rapidly as the temperature rises. Under normal circumstances, the resistance of the element does not change with the length of time of use, so the old and new silicon molybdenum rod electric heating elements can be mixed.
The silicon carbide rod is a non-metallic electric heating element. It is made of high-purity green hexagonal silicon carbide as the main raw material and recrystallized at a high temperature of 2200℃. The normal use temperature can reach 1450℃. Under reasonable use conditions, it can be used continuously for more than 2000 hours. It is used in the air without any protective atmosphere. Suitable for all kinds of electric furnaces.
