MoSi2 Heater 1750℃ Tunnel Kiln

Mosi2 Heater General Description:

Mosi2 Heater is a kind of resistance heating element made from Molybdenum Disilicide. It can be exerted under the high temperature of the oxidated atmosphere. MoSi2 heating element rod has the unique function of high temperature anti-oxidation. Under the oxidated atmosphere, the maximum temperature of MoSi2 elements is 1800°C. It can be made into various types, including U-type, W-type, right-angle as well as circular type.

The general temperature of MoSi2 rod heating element is from 1300°C to 1800°C, which is universally applied to the field of metallurgy, glass, ceramics, magnetic matrials, refractory materials, crystals, electron devices and kiln etc. It is the ideal heating element of high temperature anealing.

Following should be provided when ordering Mosi2 Heater :

• Grade: 1700, 1800 or 1900
• Diameter: D1/D2, in/in or mm/mm
• Heated Length: Le*, in. or mm
• Terminal length: Lu*, in. or mm
• Shank Spacing: A*, in. or mm
• Specify Le, Lu and A with the same units (e.g. all as in. or mm).

Mosi2 Heater Examples:

U-Shape, Material Grade 1800, D1=3mm, D2=6mm, Le=140mm, Lu=125mm, A=25mm

Specify as: MS18U, 3/6 x 140 x 125 x 25

1. Physical Properties of MoSi2 Heating Element

2. 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.
