1700 Degree Molybdenum Disilicide Heating Elements U Type
Molybdenum Disilicide Heating Elements is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, on the surface of MoSi2 heater owing to the high temperature combustion a layer of compact quartz protective film is formed to prevent MoSi2 from continuously oxidizing.
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
Molybdenum Disilicide Heating Elements Parameters
* Shape: I, U, UL, W, WL, Irregular
* Diameter: 3/6, 4/9, 6/12, 7/12, 7/14, 9/18, 12/24(mm)
* Temperature: 1700°C, 1750°C, 1800℃
Physical property of Silicon Molybdenum Rod :
| Physical properties | ||||
| Volume Density | Bend Strength | Porosity Rate | Water Absorption | Hot Extensiblity |
| 5.5-5.6g/cm³ | 15-25kg/ cm2 | 7.4% | 1.2% | 4% |
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.
