Super 1800C Mosi2 Heating Element Heater High Efficiency Dental
Furnace
MoSi2 Heating Element introduction :
Mosi2 heating element is a special product combined metal and
ceramics. So it has the characteristics of silicon and molybdenum.
Molybdenum disilicide (MoSi2) is a refractory metal silicide that
is primarily used as a heating element.
In recent years, its potential for use as a structural ceramic has
been recognised, as the material combines excellent oxidation
resistance and high elastic modulus at elevated temperatures.
Precaution for use:
1. The 1700C MoSI2 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.
