Special Shape MoSi2 heater

The MoSi2 heating element is a dense cermet material consisting of MoSi2 and an oxide, glassy phase component.
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 utilization 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.

1. Moly-D heating elements are manufactured to industry established resistance values. The same spacing, power ratings and voltages, used with other molybdenum disilicide elements can be used.

2. Most sizes and types can be shipped 2 to 3 weeks after receipt of an order. Emergency shipments for 3/6 and 6/12 can usually be made in 2 to 3 days.

3. We can assist you in choosing the most suitable element material and element type for your application. We also offer free engineering service for a new furnace design or a conversion from gas or oil fired to electric heating.
