. The General Description of molybdenum disilicide(mosi2) heating element
MoSi2 heaters 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.
We make U type, W type, rod etc. The dimension ranges from 3/6, 4/9, , 6/10, 6/12, 6/14, 7/14, 8/16, 9/18 to 12/24mm. Special request from customers is welcome.
The MoSi2 Heating Elements belong to the brittleness material so that they are easy to rupture at the normal temperature, which brings some difficulty to transport and install, but it may be avoided if they were installed and used correctly.
2. Physical and Chemical Properties of Molybdenum Disilicide(mosi2) heaters
1) Physical property
2)Recommend Surface load
Furnace Temp (C )
Surface load of hot zone(w/cm2)
MoSi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700° C, the MoSi2 heating element must not be used in the temperature between 400° C and 700° C for a long time; Otherwise the element will be cremated under the strong oxidizing function in the low temperature.
It should be pointed out that element cannot be used for rather long time in 400-700° C, or it will be powdered owing to the strong oxidizing action in low temperature.
3. Electric Property of Molybdenum Disilicide(Mosi2) heating Element
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
