The General Descrioition of Mosi2 Furnace Heater

Torch furnace mosi2 heating element has been manufacturing Molybdenum disilicide (MoSi2) heating elements since 1978. Specifically made for industrial and laboratory furnaces, the MoSi2 heating elements are a ceramic based resistant element that can produce furnace temperature to 1850C. 
These custom heating elements are known for their longevity and reliability at a high temperature.The U shaped elements are most frequently used suspended with the bottom of the "U" down. The element consists of two cold ends (Lu) and a U-shaped hot section (Le). The cold ends are twice the diameter of the hot section and are attached by a weld. The extremities of the cold ends are metallized with aluminum to provide a low-resistance contact surface to which the electrical connections are made with flat braided aluminum straps.These elements are available in two grades: MS1700 for element temperatures up to 1700 deg C and MS1800 for element temperatures up to 1850 deg C.

Chemical Properties
MoSi2 Heating Element has the ability to withstand oxidation at high temperatures. This is due to the formation of a thin and adhesive protective layer of quartz glass (SiO2) on the surface. When the element temperature over 1700℃, SiO2 protective layer which melting point is 1710℃ was fused, and because of the surface tension, it fused into drops, which is useless. However, when element continue working in oxidizing atmospheres, the SiO2 protective layer is spontaneously rebuilt.
Notice: It is no good to use Molybdenum Disilicide Heating Element for Long-term within a range of 400-700℃, otherwise the element will be powdered by the strong low temperature oxidation..

 Installation of Mosi2 Furnace Heater
1)Vertically hanging
Under normal temperature, MoSi2 element is very brittleness,while under high temperature it is plasticity.So,the better way for installation if the U Shape element is to hang it vertically,to the furnace top through the support clamping chuck H.The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end ,or the element will easily be broken.
2)Support clamp
Support clamp are applied to 9/18 and 6/12 two kinds of elements respectively. the support clamp supports the whole weight of the element and the position of the element is also determined by it .therefore ,it must be installed carefully to assure that the element it vertically hung.in order to prevent the element from being over heated locally,the taper part of the element lower end must put into the furnace chamber.
