 2. Chemistry Character
    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. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between **0C and **0C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.

 

     The brittleness of MoSi2 heating  element is relative more under the usual temperature, it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector cant be screwed too tightly.  When temperature of the element is going up,  please twist it tightly again, so the element is not easily broken.
 
      (our suggestion: please choose the specialize power connector provided by our company) The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top cant be over **0C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than *0mm between the low end of connector and the upside of the ceramic brick. The Dia.6 element cant be used of **0A for a long time. The Dia.9 element cant be used of **0A for a long time.)
