Special Shape Molybdenum Disilicide Heating Element Description:
The MoSi2 heating element is a dense cermet material consisting of MoSi2 and an oxide, glassy phase component. Advantages:
Molybdenum disilicide heaters have the ability to withstand oxidation at high temperatures by forming a protective layer of quartz on its surface. If this glassy phase should be exposed to contaminants, a lower melting phase forms. This material literally drips off the element exposing more molybdenum disilicide on which a new protective
oxide layer forms.
MoSi2 heater become somewhat ductile at approximately 1200 C.
Moly-D elements may be used up to a surface temperature of 1800C in oxidizing atmospheres.
Long service life and ease of replacement contribute to high furnace tilization and low maintenance costs .
New and old elements can be used together and in series.
Can dissipate high power loading.
Can be used continuously or intermittently.
Provide rapid furnace temperature ramping.
