Technical Parameters
MoSi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. The surface is vitrified at high temperature in an oxidizing atmosphere to form a bright and dense quartz (sio2) glass film, which can protect the MoSi2 heating element from oxidation. Therefore, the MoSi2 heating element has unique high temperature oxidation resistance, and the operating temperature is mostly 1700C and 1800C in oxidizing atmosphere. The common shape is U-shaped, and other shapes also can be made according to the design of the furnace.
MoSi2 heating elements are widely used in metallurgy, glass, ceramics, refractory materials, crystals, electronic components and kiln manufacturing.
Note: MoSi2 heating element should be handled lightly as it is a brittle element at normal temperature.

Use Precautions
1The product should be dried before use.
2.It should be preheated before heating the cold kiln.
3.It should be cooled and heated gradually, avoid fast cooling and heating.
4.It should be handled with care, avoid beating by sharp objects.
5.The heating part of the heater must be heated under the aluminum liquid to prevent the heater from drying in the protective tube.
6.When installing the flange, please select a high temperature resistant and flexible gasket to avoid leaking。
7.Keep regular cleaning and maintenance can prolong the service time, otherwise, the life time will be shorter.
