U shape MoSi2 Heating Elements
MoSi2 heating element is a type of resistance heating element composed of high purity Molybdenum Disilicide.When heated toa high temperature in an oxidizing atmosphere,a layer of compact quartz qlass forms on the surface of the element which withstands oxidation.In an oxidizing atmosphere,its maximum temperature canreach1800℃and its applicabletemperature is 500~1700C.It can be widely used as heating elements in high temperature furnaces for a variety of industries including ceramics, magnets, glass metallurgy, refractory and many others.

MoSi2 Heater Advantages:
A. It has anti- oxidation and automatic repair.
B. Function and can be used continually in oxidative atmosphere.
C. We are using thermal processing in shape,which maintains a very good high-temperature tenacity and plasticity of the basic materials.
D. the cold and hot end welding aspect, it uses special joint technology to take shape.
E. The product has high density that greatly improves the conductivity of the product.
F. Good surface quality, high mechanical strength and toughness.
