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.

5.Installation of elements:
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 UShape 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 veryically hungin order to prevent the element from being over heated locally,the taper part of the element lower end must put into the furnace chamber.Packaging & Shipping
