What’s theMosi2 Electric Heater 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.
Precaution for use:
1. The heating element of silicon molybdenum rod should not be used in the temperature range of 400 ℃ to 700 ℃, so under this unfavorable condition, the component will undergo low temperature oxidation and damage the component.
2. The heating element of silicon molybdenum rod is suitable for
use in air and neutral atmosphere. The reducing atmosphere such as
hydrogen will destroy the protective layer, and the steam of
chlorine and sulfur will directly damage the element.
3. Silicon molybdenum rods are somewhat softened at high
temperatures (above 1500 degrees), and they are hard and brittle at
low temperatures. In order to avoid stress during temperature
changes, which is conducive to thermal expansion and contraction of
components, it is best to use a free vertical hanging installation
method . The disassembly and replacement of the hoisting components
is more convenient. It is not necessary to wait for the furnace to
cool down, and it can be replaced in a hot state.
