MoSi2 Heating Element Of 1750 ℃ High Temperature Tubular Electric Furnace
MoSi2 Heating Element Of 1750 ℃ High Temperature Tubular Electric Furnace
MoSi2 Heating Element Description:
Mosi2 heating element is a type of resistance heating elemnet composed of high perity molybdenum disilicide. When heated to a high temperature in an oxidizing atmosphere,a layer of compact quartz glass forms on the surface of the element which withstands oxidation. In an oxidizing atmosphere, its maximum temperature can reach 1800℃,and its applicable temperature is 500-1700℃. It cna be widely used as heating elements in high temperatuer furnaces for a varity of industried including ceramics, magents, glass, metallurgy, refractory and many others. We named our Mosi2 heating elements as Synthe super.
MoSi2 Heating Element 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 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.

- Chemical Properties of Physical Properties of MoSi2 Heating Element
Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent Mosi2 from oxidizing more. When the element temperature is higher than 1700 °C, the film becomes melting. It’s not suitable for long time use in the temperature range of 400-700°C, otherwise, the element will be powdering for the strong oxidation under low temperature.
