Moly-D® Molybdenum Disilicide Heating Elements
High Temperature Heating Elements for Electric Furnaces
Moly-D® Molybdenum Disilicide (MoSi2) Heating Elements are used in electric furnaces to deliver heating at temperatures as high as 3,362ºF (1,850ºC). Used in production furnaces, laboratory equipment, glass melting and many other applications, these elements are available in a number of different configurations and available with custom design options to meet the specific needs of your facility or operations.
Moly-D Molybdenum Disilicide (MoSi2) Element Description
The Moly-D element is a dense cermet material consisting of MoSi2 and an oxide, glassy phase component.
Moly-D elements 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.
Moly-D elements become somewhat ductile at approximately 1200ºC (2190ºF).
