MoSi2 heating elements for SEMICONDUCTOR, Diffusion and LPCVD furnaces for silicon wafers
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.
Molybdenum Disilicide Heating Elements Feature
1. High temperature for various electric furnaces.
2. Long life combined with ease of replacing failed elements
3. Can be used continuously or intermittently
4. New and old elements can be connected in series
5. High power concentration may be applied

Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent Mosi2 from oxidizing more. When the element temperature is higher than 1700 °C, the film becomes melting. It’s not suitable for long time use in the temperature range of 400-700°C, otherwise, the element will be powdering for the strong oxidation under low temperature.
