MoSi2 Heating Element introduction :
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.
UNIQUE PROPERTIES
Moly-D heating elements are manufactured by powder metallurgy. They consist of molybdenum disilicide with additives that prevent recrystallization. Since Moly-D is completely stable up to 1800ºC (3270°F), it surpasses other heating element types for high temperature performance.
The resistance of Moly-D elements to oxidation lies in the formation of an impermeable quartz, or glass-like protective layer which re-forms when heated if damaged in operation.
The Moly-D element has a low specific electrical resistivity with a positive resistance-temperature characteristic. It can be used at a very high watt loading compared to metallic heating elements. Because of its high temperature oxidation resistance, Moly-D electrical resistance remains constant at constant temperature over its useful life. This permits the use of old and new elements together in the same furnace, even if series-connected.
TEMPERATURE RANGE
Maximum element temperature depends on the atmosphere within the furnace chamber. In air this is 1800ºC (3270°F). Since element surface temperature exceeds furnace ambient in relation to the watt loading, careful attention must be given to these parameters for satisfactory element performance.
Moly-D heating elements normally operate between 1300 and 1750ºC (2372-3182°F). Moly-D elements may be used below 1300ºC (2372°F) particularly for furnace atmospheres harmful to silicon carbide heating elements (e.g., sulfur dioxide, water-steam, etc.). Moly- D should not be used between the temperature range of 400 and 700ºC (752-1292°F), where a destructive low temperature oxidation may occur called pest.
