1.The General Description
MoSi2 heating elements are resistive heating elements based on molybdenum disilicide. The molybdenum disilicide heating elements prevents the inner core from oxidation by forming a compact quartz glass coating at the surface under high temperature. The temperature generated by MoSi2 goes as high as 1700~1800°C in oxidation atmosphere. They can be widely used in such applications as sintering and heat treatment on electronic ceramics, structural ceramics, magnetic materials, flameproof materials, glass, metallurgy, etc. The resistance of the heating elements is independent on their mission time. The MoSi2 heating elements hardly age, which allows the mixed use of new and old packages.
2.Physical Properties of Elements
Volume density | 5.5~5.6kg/cm3 | Bend strength | 515~25kg/cm2 |
Vickers-hardness | (HV)570kg/mm2 | Porosity rate | 7.4% |
Water absorption | 1.2% | Hot extensibility | 4% |
3.Electric Property of Elements
1) Resistance property
The resistivity of element rapidly rises as the temperature rises,under normal operating conditions ,generally the element resistance doesn't change with the service time changing.So the old and new elements can be used mixed.
2) Surface load
The key factor to the optimum service life of the element is to select the surface load of the element correctly according to the furnace construction,atmosphere and temperature.Right figure shows the relation between the furnace and the element surface load under the condition that the element radiation isn't obstructed.The shadow part in the figure shows the surface load-temperature range in common use.The figure still shows the reference current.
