Molybdenum Disilicide Rod Heating Elements for Dental Sintering
Furnace
Molybdenum Disilicide Rod Application:
SUPER 1700, 1800 type molybdenum disilicide rod for dental sintering
furnace are extensively used in the industries of metallurgy,
glass, ceramic refractory,crystal electronic device, industrial
furnace manufacture, etc.. It is an essential ideal element when
the products are sintering in the high temperature.
Attention: MoSi2 elements can not be used in 400 to 700 °C for a
long time, otherwise, it will be powered and damaged due to strong
oxidizing action in low temperature.
* Shape: I, U, UL, W, WL, Irregular
* Diameter: 3/6, 4/9, 6/12, 7/14, 9/18, 12/24(mm)
* Temperature: 1700°C, 1750°C, 1800℃
Molybdenum Disilicide Rod have good resistance characteristic, so it is an ideal heating
material to replace traditional heating elements.
Resistivity of MoSi2 (Molybdenum Disilicide) heating element rises dramatically when temperature rises. Power
output is less than 35% of the max. output at 300°C. Resistance of a MoSi2 heating element does not change under normal use, and you can mix
new and old elements together.
Generally a separator should be placed in between two shanks of
heating element when installing the heating elements in the
furnace. Please make sure the width of the separator matches the
space of the heating element. If the separator is too big it may
break the heating element during installation
